Do octopus have brains

TED-Ed, Cláudio L. Guerra. An octopus is a lot brainier than you might imagine considering one of its closest living relatives is a sea slug. In fact, some scientists argue it could be the first intelligent being on the planet. They can complete puzzles, untie knots, open jars and toddler proof cases, and are expert escape artists from aquariums.

One of the really neat things about cephalopods is that even though they have a centralized brain, they also have a highly distributed nervous system. Lots of processing, even “thinking,†can happen throughout the body. Octopus arms can control much of their own movement, and the body of the squid may be able to control itself. A.
