Went to see One Man, Two Guvnors at the Adelphi Theatre with S, O and F. Really very good. Though it turns out the audience interactions with the sandwich are set pieces.
There was an interesting study published this week which looked at 1,000 search terms in Google and measured the rankings for Wikipedia.org, which posed the question does Google give too much prominence to Wikipedia?
As a quick recap, Wikipedia ranked for a huge 99% of the terms (as selected with a random noun generator).
While many people may consider this an unfair bias from Google towards Wikipedia, I’m not so sure…
There’s no denying that 99% is an extremely high volume of keywords to be ranking for and this is a very interesting study to highlight Wikipedia’s dominance.
However, I’m still not that surprised by the results. Wikipedia has seemingly become every SEOs biggest competitor, which explains why its dominance in Google creates a lot of attention.
But if you look deeper into the reasons why the site is ranking. Despite so many top rankings, I honestly believe they deserve to be ranking where they are.
I certainly don’t think there’s anything non-algorthimic happening here, as some people have alluded to in the past.
Why does Wikipedia dominate Google?
To back up the reasoning for the site being the number one performer for organic search in the world, Wikipedia probably has the best set of SEO fundamentals on the web:
Unique and in-depth content
Wikipedia is such a great case study for the power of UGC (user generated content) with huge volumes of content which is written in extremley large detail.
For example, the Wikipedia Turkey page (which was in the sample list of 1,000 terms) contains 12,536 words on that single page and the breadth of Wikipedia’s content stretches to 70 million indexed pages in Google across 10 languages!
Targeted webpages for key terms
Each page is written individually around a primary search term, and due to the fact that this is both a strong page and domain, it’s likely to rank both for these core search terms and a long-tail of traffic (and with 12,000+ keywords on a page – that’s a very long tail!)
Very strong domain authority
Great internal linking structure
Wikipedia does a great job of contextual linking internally, allowing it to spread the domain strength across the site. If only it would remove that nofollow and link more externally!
Excellent page authority
Wikipedia is clearly the market leader in the online encyclopedia world (Encarta who?) , so naturally generate links and citations from high quality sources.
If you take a look at the same “Turkey” webpage – this has 21,375 links going directly to that page – many of which are from authority sources such as the BBC, Telegraph and NASA!
Combine that with such a strong domain and it’s becoming a lot clearer as to the reasons why they rank so well.
But will this dominance last?
Based on SEO metrics alone, most notably content and links I would say yes. Wikipedia is such a strong site that it will be very difficult to shift this trend.
The main thing I would see as a threat to them would be seeing how Google’s algorithm develops towards analysing user intent.
For example, if a searcher is looking for “Turkey” (one of the terms listed in the study) and is expecting to find travel and holiday packages, they may be disappointed to find an informational page about the country instead.
So if Google starts paying more attention to bounce rates and user experience, I could see Wikipedia losing some of its top rankings in the future, especially for more transactional queries.
However, seeing the site slide off of page one completely is unlikely in my opinion. Mainly because Google seems to be a strong believer in “query deserves diversity” and Wikipedia generally provides content that no other site can offer for a huge range of keywords.
How do you take advantage of this as an SEO?
As I mentioned above, Wikipedia is every SEOs competitor. Whether you like it or not, it may not be directly competing for business in your market but it is competiting for rankings and traffic in your market, which generates your business.
So if you know it ranks highly in Google, why not use that information to dig a bit deeper? Analyse how much traffic it’s getting, there’s a great tool which shows you the traffic for an individual article on Wikipedia – see this for the Turkey page as an example:
This tells you that Wikipedia has generated 1,038,886 visits in the last 90 days and that it’s the 253rd most popular article on Wikipedia.
Plus, you can dig deeper still if you have paid tools such as Hitwise, SearchMetrics or SEMRush, trying to find out which keywords Wikipedia generate traffic from and then optimising and targeting traffic from them.
What do you think?
Do you agree that Wikipedia’s rankings are fair? And lets face it, even if they’re not (unless you’re Google of course) what can we do about it other than try and compete. We might as well try and learn something from the site’s huge success of user-generated content creation and find out how we can use it to strengthen our own sites.
In our recently published Digital Marketing and E-Commerce Careers Guide, we have included detailed information about how senior digital professionals can improve their career. In all, 17 well respected industry figures provided over 10,000 words of constructive advice on what digital marketers can do to fast track their careers. However, with so much good material, we simply couldn’t fit it all in. Over the next coming weeks, we want to share with you some of the best advice we received.
This week those leaders answer the question, “What attributes are most highly sought after in senior digital professionals?”
Allison Wightman, Head of eBusiness, Virgin Atlantic
Senior digital professionals need the ability to define, articulate and communicate a strategic digital vision for the rest of the business, which often goes far beyond the remit of the department they work in or the accountability they have. They also need to be able to keep abreast of new technologies and devices and translate what’s applicable to the business that they are in.
Andy Harding, Director of E-commerce, House of Fraser
- A customer centric outlook
- Passion for data
I expect all senior digital people to have a really good understanding of usability – if you can’t see things from a customer’s point of view, you will make bad decisions.
Angus Cormie, Online Director, Dell EMEA
There are two equal attributes; a passion for customer experience, and business acumen. The former will drive flawless execution as well as innovation in the online and digital journeys we want our customers to take. The latter enables the digital professional to determine the viability, maintainability, and overall ROI for these experiences and innovations, and ultimately enables a digital expert to articulate to non-digital executives their impact.
Chris Ketley, Head of Digital and E-commerce, BUPA
- Clear vision, able to set and drive the strategic agenda for digital.
- Competency in managing the tactical detail and prioritising day to day demands balanced in parallel with developing the longer term strategic priorities.
- Strong leadership, capable of motivating at all levels in the organisation, not just the digital team.
- Focused on the customer, informed about competitors and commercial in orientation; able to identify and deliver the customer and business benefits.
- Good communicator – managers need to influence senior management and stakeholders.
- No substitute for relevant expertise and experience (preferably in both on and offline marketing as these need to align).
- Resilience, persistence and patience: helping others in the organisation who won’t necessarily share the knowledge or have the passion for digital that you as the senior digital manager must have.
Alison Lancaster, CMO, Kiddicare, and Marketing Director, Morrison’s Non-Food
Professionals need experience. This means solid, proven understanding, with demonstrable success in the online space. They also require a level of expertise and executional excellence.
They require the ability to analyse, interpret and effectively communicate digital data and KPIs into deep customer understanding and actionable insights, and use this to create and enable better digital strategies and campaigns. Customers can then enjoy a more rewarding and entertaining multichannel journey and a successful brand/shopping experience. They also need the ability to lead and engage people, to get the most out of internal and external teams.
Finally, they need to be enterprising, possessing solid commercial trading skills to maximise traffic, sales and increase brand awareness and customer loyalty.
Russell Gould, Former Managing Director, e-StrategyConsultancy.com
Leadership, ability to motivate, some sense of vision, ability to communicate and the ability to make quick informed strategic decisions. Experience is also very important but someone with all the above mentioned attributes will be more sought after than someone with bucket loads of ecommerce experience. In effect digital is no different to any other senior management position – good senior managers have all of the above.
Luca Benini, Managing Director Europe, Buddy Media
One of the most important attributes is the ability to adapt. At cutting-edge tech companies, things change so quickly that someone stuck in their ways won’t be able to survive. Being able to rapidly change courses and quickly create a new plan is huge in this space.
Rosalie Kurton, Head of New Business, LBi
Digital professionals need to be highly strategic, good at problem solving, good with people and a good motivator, and possess a strong focus on quality of service and output.
Tessa Cook, E-commerce Managing Director, Dyson
As with any key position in business, leadership, strategy and people management are the most important attributes. Specific skills and experience come second.
An ability to influence multiple stakeholders is essential, as almost every digital project cuts across many disciplines, teams or business units
You also need the ability to prioritise ruthlessly. There are a million and one things that we want to do, or could do. But only a few of them will really shift the dial. You need to identify what those few things are, and stay focused on them and try to ignore the noise!

Article in UK AuthorITy magazine, following Nick and my webchat in December.
How do you know when your website works? When it comes to improving public services the answer may not always be obvious – but it is vital to set targets and measure against them. Dan Jellinek reports from ITU Live.
It is important for public bodies to know whether or not their websites are working, but managers sometimes focus on softer measures which are hard to interpret such as ‘how many visits did we get?’ Peter Jordan, product analytics lead in the Government Digital Service (GDS) delivery team, told the ITU Live panel.
For an e-commerce website the hard measure is obvious – sales – but for public sector sites the equivalent is to look for tasks completed, Jordan said. “Like how many people started out on a transaction to renew car tax and completed it: that’s analogous to buying a pair of shoes.”
Nick Breeze, senior customer insight manager at the GDS, said the importance of online task completion is that otherwise “they may need to pick up the phone, which is very costly”. One method the GDS has used to measure task completion, alongside more established methods such as live user testing, is to issue tracking software to larger numbers of people which can monitor their web use at home and report on what keystrokes they make, where they go and how long it takes to complete a task.
“One of the reasons we started to use it are the sheer cost efﬁ ciencies. We’re tracking 1,600 users, which is costing us a fraction of what it would face-to-face,” Breeze said. However, the most valuable insights come from combining different kinds of data, such as tying together what people say in online surveys with what they are actually did, said Alex Henry, online segmentation and personalisation expert at Adobe UK. So if someone reports a poor experience with a form, and then you can see they spend 10 minutes on page 4 of that form, you know where the improvements are needed. Even more sophisticated data matching is needed to track the correlations between website use and call centre use, Henry said.
“You could just look at the raw data and say ‘Here are my call centre numbers, here’s the activity I’ve done online, now let’s compare in a few weeks’ time to see if my call centres have gone down’. Or you can go down to the level where you’re giving web users a tailored phone number for example, once they get to a certain point in their journey, so that you can prep the call centre.
“So we have the same identiﬁ er in different data sources to say, ‘Here’s someone who is online, here’s how they interacted with the call centre, and here’s the summation of what happened’. We’re seeing a lot of effort at the moment now where clients are taking online behaviour, tying it in with online survey responses and then comparing that with call centre data to see what’s going wrong.”
It is also important to combine and consider many sources of data when designing a website, said Jordan, including trafﬁc data; the public body’s own business needs, and another hugely important source of information on what questions citizens want answered: search data. “In terms of web trafﬁc about 60% comes from web search: Google, Bing, Yahoo and so on – by far the biggest portion. So making sure you’re optimised for search is really important.”
There is plenty of good free material on search engine optimisation out there provided by Google and others, Jordan said – “just search for it”. Basically it breaks down into a research phase and production phase. “So say you’re talking about mountains, you should research the terminology people are actually using – they might be using peaks rather than mountains – or you may see there is a big gap about the Pyrenees where everybody is writing about the Alps, and then build that terminology into what you’re writing about.” Other important factors include increasing your links with social media, he said.
Finally, the panel turned to the controversial subject of cookies – small ‘strings’ or pieces of information delivered by a website and saved locally onto a user’s machine to help determine when the same user is returning, and tailor the response accordingly. “There is a lot of misconception about what a cookie actually contains,” Henry said. “Take my mum, for example, who might browse a leading retailer’s website: she’ll then go back to her web-based email account and, on the right-hand side, she’ll see a very similar object to what she’s just browsed. And her interpretation of that is, ‘Oh they were watching me, I don’t like that’. “But actually, the advert’s always going to be there, are you happy for it to be more tailored to you, or would you just want something generic, and do you really mind? It’s still your choice whether you interact with that advert or not. Because it’s more relevant, people think the cookie’s reading everything they’re doing, which it absolutely isn’t.”
Cookies are useful for government sites because they add detail to information on customer journeys, Jordan said. “There’s stuff that analytics can tell you without cookies, but you do lose sight of that anonymised personal information. To me, the way forward is around education and transparency about what you’re doing with cookies.” During the live session, an online poll of viewers delivered some interesting results on whether or not public sector website owners have already taken action to implement the EU privacy directive, which stipulates that all
UK organisations must obtain consent from their website users to place cookies on their computers by May 2012. Only around 8% of respondents said they already had new cookie policies, while 46% said they had not yet, but intended to in 2012; and the same number said they were waiting for further advice from the UK government before taking action.
So while all respondents accepted that some kind of action is bound to be needed, many are still waiting for clear guidance on cookies. But with just a few months to go to the compliance deadline there is not a lot of time to play with: cookies are now a hot topic.
Inside the mind of the octopus

ON AN UNSEASONABLY WARM day in the middle of March, I traveled from New Hampshire to the moist, dim sanctuary of the New England Aquarium, hoping to touch an alternate reality. I came to meet Athena, the aquarium’s forty-pound, five-foot-long, two-and-a-half-year-old giant Pacific octopus.
For me, it was a momentous occasion. I have always loved octopuses. No sci-fi alien is so startlingly strange. Here is someone who, even if she grows to one hundred pounds and stretches more than eight feet long, could still squeeze her boneless body through an opening the size of an orange; an animal whose eight arms are covered with thousands of suckers that taste as well as feel; a mollusk with a beak like a parrot and venom like a snake and a tongue covered with teeth; a creature who can shape-shift, change color, and squirt ink. But most intriguing of all, recent research indicates that octopuses are remarkably intelligent.
Many times I have stood mesmerized by an aquarium tank, wondering, as I stared into the horizontal pupils of an octopus’s large, prominent eyes, if she was staring back at me—and if so, what was she thinking?
Not long ago, a question like this would have seemed foolish, if not crazy. How can an octopus know anything, much less form an opinion? Octopuses are, after all, “only” invertebrates—they don’t even belong with the insects, some of whom, like dragonflies and dung beetles, at least seem to show some smarts. Octopuses are classified within the invertebrates in the mollusk family, and many mollusks, like clams, have no brain.
Only recently have scientists accorded chimpanzees, so closely related to humans we can share blood transfusions, the dignity of having a mind. But now, increasingly, researchers who study octopuses are convinced that these boneless, alien animals—creatures whose ancestors diverged from the lineage that would lead to ours roughly 500 to 700 million years ago—have developed intelligence, emotions, and individual personalities. Their findings are challenging our understanding of consciousness itself.
I had always longed to meet an octopus. Now was my chance: senior aquarist Scott Dowd arranged an introduction. In a back room, he would open the top of Athena’s tank. If she consented, I could touch her. The heavy lid covering her tank separated our two worlds. One world was mine and yours, the reality of air and land, where we lumber through life governed by a backbone and constrained by jointed limbs and gravity. The other world was hers, the reality of a nearly gelatinous being breathing water and moving weightlessly through it. We think of our world as the “real” one, but Athena’s is realer still: after all, most of the world is ocean, and most animals live there. Regardless of whether they live on land or water, more than 95 percent of all animals are invertebrates, like Athena.
The moment the lid was off, we reached for each other. She had already oozed from the far corner of her lair, where she had been hiding, to the top of the tank to investigate her visitor. Her eight arms boiled up, twisting, slippery, to meet mine. I plunged both my arms elbow deep into the fifty-seven-degree water. Athena’s melon-sized head bobbed to the surface. Her left eye (octopuses have one dominant eye like humans have a dominant hand) swiveled in its socket to meet mine. “She’s looking at you,” Dowd said.
As we gazed into each other’s eyes, Athena encircled my arms with hers, latching on with first dozens, then hundreds of her sensitive, dexterous suckers. Each arm has more than two hundred of them. The famous naturalist and explorer William Beebe found the touch of the octopus repulsive. “I have always a struggle before I can make my hands do their duty and seize a tentacle,” he confessed. But to me, Athena’s suckers felt like an alien’s kiss—at once a probe and a caress. Although an octopus can taste with all of its skin, in the suckers both taste and touch are exquisitely developed. Athena was tasting me and feeling me at once, knowing my skin, and possibly the blood and bone beneath, in a way I could never fathom.
When I stroked her soft head with my fingertips, she changed color beneath my touch, her ruby-flecked skin going white and smooth. This, I learned, is a sign of a relaxed octopus. An agitated giant Pacific octopus turns red, its skin gets pimply, and it erects two papillae over the eyes, which some divers say look like horns. One name for the species is “devil fish.” With sharp, parrotlike beaks, octopuses can bite, and most have neurotoxic, flesh-dissolving venom. The pressure from an octopus’s suckers can tear flesh (one scientist calculated that to break the hold of the suckers of the much smaller common octopus would require a quarter ton of force). One volunteer who interacted with an octopus left the aquarium with arms covered in red hickeys.
Occasionally an octopus takes a dislike to someone. One of Athena’s predecessors at the aquarium, Truman, felt this way about a female volunteer. Using his funnel, the siphon near the side of the head used to jet through the sea, Truman would shoot a soaking stream of salt water at this young woman whenever he got a chance. Later, she quit her volunteer position for college. But when she returned to visit several months later, Truman, who hadn’t squirted anyone in the meanwhile, took one look at her and instantly soaked her again.
Athena was remarkably gentle with me—even as she began to transfer her grip from her smaller, outer suckers to the larger ones. She seemed to be slowly but steadily pulling me into her tank. Had it been big enough to accommodate my body, I would have gone in willingly. But at this point, I asked Dowd if perhaps I should try to detach from some of the suckers. With his help, Athena and I pulled gently apart.
I was honored that she appeared comfortable with me. But what did she know about me that informed her opinion? When Athena looked into my eyes, what was she thinking?
WHILE ALEXA WARBURTON was researching her senior thesis at Middlebury College’s newly created octopus lab, “every day,” she said, “was a disaster.”
She was working with two species: the California two-spot, with a head the size of a clementine, and the smaller, Florida species, Octopus joubini. Her objective was to study the octopuses’ behavior in a T-shaped maze. But her study subjects were constantly thwarting her.
The first problem was keeping the octopuses alive. The four-hundred-gallon tank was divided into separate compartments for each animal. But even though students hammered in dividers, the octopuses found ways to dig beneath them—and eat each other. Or they’d mate, which is equally lethal. Octopuses die after mating and laying eggs, but first they go senile, acting like a person with dementia. “They swim loop-the-loop in the tank, they look all googly-eyed, they won’t look you in the eye or attack prey,” Warburton said. One senile octopus crawled out of the tank, squeezed into a crack in the wall, dried up, and died.
It seemed to Warburton that some of the octopuses were purposely uncooperative. To run the T-maze, the pre-veterinary student had to scoop an animal from its tank with a net and transfer it to a bucket. With bucket firmly covered, octopus and researcher would take the elevator down to the room with the maze. Some octopuses did not like being removed from their tanks. They would hide. They would squeeze into a corner where they couldn’t be pried out. They would hold on to some object with their arms and not let go.
Some would let themselves be captured, only to use the net as a trampoline. They’d leap off the mesh and onto the floor—and then run for it. Yes, run. “You’d chase them under the tank, back and forth, like you were chasing a cat,” Warburton said. “It’s so weird!”
Octopuses in captivity actually escape their watery enclosures with alarming frequency. While on the move, they have been discovered on carpets, along bookshelves, in a teapot, and inside the aquarium tanks of other fish—upon whom they have usually been dining.
Even though the Middlebury octopuses were disaster prone, Warburton liked certain individuals very much. Some, she said, “would lift their arms out of the water like dogs jump up to greet you.” Though in their research papers the students refer to each octopus by a number, the students named them all. One of the joubini was such a problem they named her The Bitch. “Catching her for the maze always took twenty minutes,” Warburton said. “She’d grip onto something and not let go. Once she got stuck in a filter and we couldn’t get her out. It was awful!”
Then there was Wendy. Warburton used Wendy as part of her thesis presentation, a formal event that was videotaped. First Wendy squirted salt water at her, drenching her nice suit. Then, as Warburton tried to show how octopuses use the T-maze, Wendy scurried to the bottom of the tank and hid in the sand. Warburton says the whole debacle occurred because the octopus realized in advance what was going to happen. “Wendy,” she said, “just didn’t feel like being caught in the net.”
Data from Warburton’s experiments showed that the California two-spots quickly learned which side of a T-maze offered a terra-cotta pot to hide in. But Warburton learned far more than her experiments revealed. “Science,” she says, “can only say so much. I know they watched me. I know they sometimes followed me. But they are so different from anything we normally study. How do you prove the intelligence of someone so different?”
MEASURING THE MINDS OF OTHER creatures is a perplexing problem. One yardstick scientists use is brain size, since humans have big brains. But size doesn’t always match smarts. As is well known in electronics, anything can be miniaturized. Small brain size was the evidence once used to argue that birds were stupid—before some birds were proven intelligent enough to compose music, invent dance steps, ask questions, and do math.
Octopuses have the largest brains of any invertebrate. Athena’s is the size of a walnut—as big as the brain of the famous African gray parrot, Alex, who learned to use more than one hundred spoken words meaningfully. That’s proportionally bigger than the brains of most of the largest dinosaurs.
Another measure of intelligence: you can count neurons. The common octopus has about 130 million of them in its brain. A human has 100 billion. But this is where things get weird. Three-fifths of an octopus’s neurons are not in the brain; they’re in its arms.
“It is as if each arm has a mind of its own,” says Peter Godfrey-Smith, a diver, professor of philosophy at the Graduate Center of the City University of New York, and an admirer of octopuses. For example, researchers who cut off an octopus’s arm (which the octopus can regrow) discovered that not only does the arm crawl away on its own, but if the arm meets a food item, it seizes it—and tries to pass it to where the mouth would be if the arm were still connected to its body.
“Meeting an octopus,” writes Godfrey-Smith, “is like meeting an intelligent alien.” Their intelligence sometimes even involves changing colors and shapes. One video online shows a mimic octopus alternately morphing into a flatfish, several sea snakes, and a lionfish by changing color, altering the texture of its skin, and shifting the position of its body. Another video shows an octopus materializing from a clump of algae. Its skin exactly matches the algae from which it seems to bloom—until it swims away.
For its color palette, the octopus uses three layers of three different types of cells near the skin’s surface. The deepest layer passively reflects background light. The topmost may contain the colors yellow, red, brown, and black. The middle layer shows an array of glittering blues, greens, and golds. But how does an octopus decide what animal to mimic, what colors to turn? Scientists have no idea, especially given that octopuses are likely colorblind.
But new evidence suggests a breathtaking possibility. Woods Hole Marine Biological Laboratory and University of Washington researchers found that the skin of the cuttlefish Sepia officinalis, a color-changing cousin of octopuses, contains gene sequences usually expressed only in the light-sensing retina of the eye. In other words, cephalopods—octopuses, cuttlefish, and squid—may be able to see with their skin.
The American philosopher Thomas Nagel once wrote a famous paper titled “What Is It Like to Be a Bat?” Bats can see with sound. Like dolphins, they can locate their prey using echoes. Nagel concluded it was impossible to know what it’s like to be a bat. And a bat is a fellow mammal like us—not someone who tastes with its suckers, sees with its skin, and whose severed arms can wander about, each with a mind of its own. Nevertheless, there are researchers still working diligently to understand what it’s like to be an octopus.
JENNIFER MATHER SPENT MOST of her time in Bermuda floating facedown on the surface of the water at the edge of the sea. Breathing through a snorkel, she was watching Octopus vulgaris—the common octopus. Although indeed common (they are found in tropical and temperate waters worldwide), at the time of her study in the mid-1980s, “nobody knew what they were doing.”
In a relay with other students from six-thirty in the morning till six-thirty at night, Mather worked to find out. Sometimes she’d see an octopus hunting. A hunting expedition could take five minutes or three hours. The octopus would capture something, inject it with venom, and carry it home to eat. “Home,” Mather found, is where octopuses spend most of their time. A home, or den, which an octopus may occupy only a few days before switching to a new one, is a place where the shell-less octopus can safely hide: a hole in a rock, a discarded shell, or a cubbyhole in a sunken ship. One species, the Pacific red octopus, particularly likes to den in stubby, brown, glass beer bottles.
One octopus Mather was watching had just returned home and was cleaning the front of the den with its arms. Then, suddenly, it left the den, crawled a meter away, picked up one particular rock and placed the rock in front of the den. Two minutes later, the octopus ventured forth to select a second rock. Then it chose a third. Attaching suckers to all the rocks, the octopus carried the load home, slid through the den opening, and carefully arranged the three objects in front. Then it went to sleep. What the octopus was thinking seemed obvious: “Three rocks are enough. Good night!”
The scene has stayed with Mather. The octopus “must have had some concept,” she said, “of what it wanted to make itself feel safe enough to go to sleep.” And the octopus knew how to get what it wanted: by employing foresight, planning—and perhaps even tool use. Mather is the lead author of Octopus: The Ocean’s Intelligent Invertebrate, which includes observations of octopuses who dismantle Lego sets and open screw-top jars. Coauthor Roland Anderson reports that octopuses even learned to open the childproof caps on Extra Strength Tylenol pill bottles—a feat that eludes many humans with university degrees.
In another experiment, Anderson gave octopuses plastic pill bottles painted different shades and with different textures to see which evoked more interest. Usually each octopus would grasp a bottle to see if it were edible and then cast it off. But to his astonishment, Anderson saw one of the octopuses doing something striking: she was blowing carefully modulated jets of water from her funnel to send the bottle to the other end of her aquarium, where the water flow sent it back to her. She repeated the action twenty times. By the eighteenth time, Anderson was already on the phone with Mather with the news: “She’s bouncing the ball!”
This octopus wasn’t the only one to use the bottle as a toy. Another octopus in the study also shot water at the bottle, sending it back and forth across the water’s surface, rather than circling the tank. Anderson’s observations were reported in the Journal of Comparative Psychology. “This fit all the criteria for play behavior,” said Anderson. “Only intelligent animals play—animals like crows and chimps, dogs and humans.”
Aquarists who care for octopuses feel that not only can these animals play with toys, but they may need to play with toys. An Octopus Enrichment Handbook has been developed by Cincinnati’s Newport Aquarium, with ideas of how to keep these creatures entertained. One suggestion is to hide food inside Mr. Potato Head and let your octopus dismantle it. At the Seattle Aquarium, giant Pacific octopuses play with a baseball-sized plastic ball that can be screwed together by twisting the two halves. Sometimes the mollusks screw the halves back together after eating the prey inside.
At the New England Aquarium, it took an engineer who worked on the design of cubic zirconium to devise a puzzle worthy of a brain like Athena’s. Wilson Menashi, who began volunteering at the aquarium weekly after retiring from the Arthur D. Little Corporation sixteen years ago, devised a series of three Plexiglas cubes, each with a different latch. The smallest cube has a sliding latch that twists to lock down, like the bolt on a horse stall. Aquarist Bill Murphy puts a crab inside the clear cube and leaves the lid open. Later he lets the octopus lift open the lid. Finally he locks the lid, and invariably the octopus figures out how to open it.
Next he locks the first cube within a second one. The new latch slides counterclockwise to catch on a bracket. The third box is the largest, with two different locks: a bolt that slides into position to lock down, and a second one like a lever arm, sealing the lid much like the top of an old-fashioned glass canning jar.
All the octopuses Murphy has known learned fast. They typically master a box within two or three once-a-week tries. “Once they ‘get it,’” he says, “they can open it very fast”—within three or four minutes. But each may use a different strategy.
George, a calm octopus, opened the boxes methodically. The impetuous Gwenevere squeezed the second-largest box so hard she broke it, leaving a hole two inches wide. Truman, Murphy said, was “an opportunist.” One day, inside the smaller of the two boxes, Murphy put two crabs, who started to fight. Truman was too excited to bother with locks. He poured his seven-foot-long body through the two-inch crack Gwenevere had made, and visitors looked into his exhibit to find the giant octopus squeezed, suckers flattened, into the tiny space between the walls of the fourteen-cubic-inch box outside and the six-cubic-inch one inside it. Truman stayed inside half an hour. He never opened the inner box—probably he was too cramped.
Three weeks after I had first met Athena, I returned to the aquarium to meet the man who had designed the cubes. Menashi, a quiet grandfather with a dark moustache, volunteers every Tuesday. “He has a real way with octopuses,” Dowd and Murphy told me. I was eager to see how Athena behaved with him.
Murphy opened the lid of her tank, and Athena rose to the surface eagerly. A bucket with a handful of fish sat nearby. Did she rise so eagerly sensing the food? Or was it the sight of her friend that attracted her? “She knows me,” Menashi answered softly.
Anderson’s experiments with giant Pacific octopuses in Seattle prove Menashi is right. The study exposed eight octopuses to two unfamiliar humans, dressed identically in blue aquarium shirts. One person consistently fed a particular octopus, and another always touched it with a bristly stick. Within a week, at first sight of the people, most octopuses moved toward the feeders and away from the irritators, at whom they occasionally aimed their water-shooting funnels.
Upon seeing Menashi, Athena reached up gently and grasped his hands and arms. She flipped upside down, and he placed a capelin in some of the suckers near her mouth, at the center of her arms. The fish vanished. After she had eaten, Athena floated in the tank upside down, like a puppy asking for a belly rub. Her arms twisted lazily. I took one in my hand to feel the suckers—did that arm know it had hold of a different person than the other arms did? Her grip felt calm, relaxed. With me, earlier, she seemed playful, exploratory, excited. The way she held Menashi with her suckers seemed to me like the way a long-married couple holds hands at the movies.
I leaned over the tank to look again into her eyes, and she bobbed up to return my gaze. “She has eyelids like a person does,” Menashi said. He gently slid his hand near one of her eyes, causing her to slowly wink.
BIOLOGISTS HAVE LONG NOTED the similarities between the eyes of an octopus and the eyes of a human. Canadian zoologist N. J. Berrill called it “the single most startling feature of the whole animal kingdom” that these organs are nearly identical: both animals’ eyes have transparent corneas, regulate light with iris diaphragms, and focus lenses with a ring of muscle.
Scientists are currently debating whether we and octopuses evolved eyes separately, or whether a common ancestor had the makings of the eye. But intelligence is another matter. “The same thing that got them their smarts isn’t the same thing that got us our smarts,” says Mather, “because our two ancestors didn’t have any smarts.” Half a billion years ago, the brainiest thing on the planet had only a few neurons. Octopus and human intelligence evolved independently.
“Octopuses,” writes philosopher Godfrey-Smith, “are a separate experiment in the evolution of the mind.” And that, he feels, is what makes the study of the octopus mind so philosophically interesting.
The octopus mind and the human mind probably evolved for different reasons. Humans—like other vertebrates whose intelligence we recognize (parrots, elephants, and whales)—are long-lived, social beings. Most scientists agree that an important event that drove the flowering of our intelligence was when our ancestors began to live in social groups. Decoding and developing the many subtle relationships among our fellows, and keeping track of these changing relationships over the course of the many decades of a typical human lifespan, was surely a major force shaping our minds.
But octopuses are neither long-lived nor social. Athena, to my sorrow, may live only a few more months—the natural lifespan of a giant Pacific octopus is only three years. If the aquarium added another octopus to her tank, one might eat the other. Except to mate, most octopuses have little to do with others of their kind.
So why is the octopus so intelligent? What is its mind for? Mather thinks she has the answer. She believes the event driving the octopus toward intelligence was the loss of the ancestral shell. Losing the shell freed the octopus for mobility. Now they didn’t need to wait for food to find them; they could hunt like tigers. And while most octopuses love crab best, they hunt and eat dozens of other species—each of which demands a different hunting strategy. Each animal you hunt may demand a different skill set: Will you camouflage yourself for a stalk-and-ambush attack? Shoot through the sea for a fast chase? Or crawl out of the water to capture escaping prey?
Losing the protective shell was a trade-off. Just about anything big enough to eat an octopus will do so. Each species of predator also demands a different evasion strategy—from flashing warning coloration if your attacker is vulnerable to venom, to changing color and shape to camouflage, to fortifying the door to your home with rocks.
Such intelligence is not always evident in the laboratory. “In the lab, you give the animals this situation, and they react,” points out Mather. But in the wild, “the octopus is actively discovering his environment, not waiting for it to hit him. The animal makes the decision to go out and get information, figures out how to get the information, gathers it, uses it, stores it. This has a great deal to do with consciousness.”
So what does it feel like to be an octopus? Philosopher Godfrey-Smith has given this a great deal of thought, especially when he meets octopuses and their relatives, giant cuttlefish, on dives in his native Australia. “They come forward and look at you. They reach out to touch you with their arms,” he said. “It’s remarkable how little is known about them . . . but I could see it turning out that we have to change the way we think of the nature of the mind itself to take into account minds with less of a centralized self.”
“I think consciousness comes in different flavors,” agrees Mather. “Some may have consciousness in a way we may not be able to imagine.”
IN MAY, I VISITED Athena a third time. I wanted to see if she recognized me. But how could I tell? Scott Dowd opened the top of her tank for me. Athena had been in a back corner but floated immediately to the top, arms outstretched, upside down.
This time I offered her only one arm. I had injured a knee and, feeling wobbly, used my right hand to steady me while I stood on the stool to lean over the tank. Athena in turn gripped me with only one of her arms, and very few of her suckers. Her hold on me was remarkably gentle.
I was struck by this, since Murphy and others had first described Athena’s personality to me as “feisty.” “They earn their names,” Murphy had told me. Athena is named for the Greek goddess of wisdom, war, and strategy. She is not usually a laid-back octopus, like George had been. “Athena could pull you into the tank,” Murphy had warned. “She’s curious about what you are.”
Was she less curious now? Did she remember me? I was disappointed that she did not bob her head up to look at me. But perhaps she didn’t need to. She may have known from the taste of my skin who I was. But why was this feisty octopus hanging in front of me in the water, upside down?
Then I thought I might know what she wanted from me. She was begging. Dowd asked around and learned that Athena hadn’t eaten in a couple of days, then allowed me the thrilling privilege of handing her a capelin.
Perhaps I had understood something basic about what it felt like to be Athena at that moment: she was hungry. I handed a fish to one of her larger suckers, and she began to move it toward her mouth. But soon she brought more arms to the task, and covered the fish with many suckers—as if she were licking her fingers, savoring the meal.
A WEEK AFTER I LAST VISITED ATHENA, I was shocked to receive this e-mail from Scott Dowd: “Sorry to write with some sad news. Athena appears to be in her final days, or even hours. She will live on, though, through your conveyance.” Later that same day, Dowd wrote to tell me that she had died. To my surprise, I found myself in tears.
Why such sorrow? I had understood from the start that octopuses don’t live very long. I also knew that while Athena did seem to recognize me, I was not by any means her special friend. But she was very significant to me, both as an individual and as a representative from her octopodan world. She had given me a great gift: a deeper understanding of what it means to think, to feel, and to know. I was eager to meet more of her kind.
And so, it was with some excitement that I read this e-mail from Dowd a few weeks later: “There is a young pup octopus headed to Boston from the Pacific Northwest. Come shake hands (x8) when you can.”
