Enter the comparative psychologists permission.
Nicola Clayton did not begin studying squid. A professor at the University of Cambridge, she has built her career around the remarkable behavior of the scrubbird, a small bluish-black bird that stores food for later. In 1998, she and her colleagues showed that birds can remember how long it’s been since food items have been hidden. they can plan for the futureThey hide food in places they have reason to believe that they will get hungry later.
Their behavior is more complex than simply knowing that food will appear if you press a button or recognize a pattern, something many animals can do. Aside from other monkeys and corvids, such as crows, few animals studied thus far possess the full range of mental abilities demonstrated by these birds.
But squid and other cephalopods It might be an interesting test case. Marine biologists have noticed that when octopuses and squid hunt, they do not follow the same route two days in a row. Comparative psychologist Kristel Josette Alves wondered if this meant that they had a memory like that of corvids, able to re-experience what happened to them in the past. In 2013, published with Dr. Clayton and his associate A puzzling study of squid Which suggests that they did. Dr. Clayton, Dr. Schnell and their colleagues began to ask: Do squids have a sense of the future and the recent past? Can they make decisions about what they think is likely to happen in the future?
Octopuses have always amazed observers with their apparent ingenuity One clip on YouTube With more than two million views, the octopus collects and takes out coconut shells, Possibly for later use as tools. Squids also have large brains and a well-developed behavior. Dr. Schnell said squid are easier to grow in the lab than squid and easier to work with than octopuses, which are often stunted and may refuse to handle a professional.
There is of course the Houdini factor, too.
“You have little entertainers escaping with the octopuses. Come in the morning and no matter how tightly you seal the aquarium, you will find them crawling.”
