Monster Seminar Jam - How Smart are Octopuses?
Dr. Roland Anderson, Biologist, Invertebrate Curator The Seattle Aquarium
Octopuses have long been known for their intelligence. They are the smartest mollusk and they are the smartest invertebrate. They can pass several intelligence tests based on what they can do or learn to do. They can learn to navigate simple mazes in the lab and they navigate their world using landmark navigation. They have distinctly different personalities. They exhibit simple play behavior. They use water as a tool, when blowing out the dirt from their dens or squirting water at an annoying fish. They can recognize individual humans but they dont have mirror self-recognition. There are over a 150 described species of octopuses but only about five species have been studied in any detail. We dont know if all species are equally as intelligent and we have no octopus IQ test to give them to see how smart they are. Even human IQ tests are questionable all cultures dont test the same. But based on what octopuses can do we can form a comparative judgment of how smart they are. Natural history details of our own giant Pacific octopus found in Puget Sound are given along with the discoveries of its intelligence found at the Seattle Aquarium and ongoing research.
