eight-legged geeks

Carl Zimmer:
So, is the octopus really all that smart? It depends on how you define intelligence. And if you've got a good definition, there are quite a few scientists who would love to hear it. Octopuses can learn, they can process complex information in their heads, and they can behave in equally complex ways. But it would be a mistake to try to give octopuses an IQ score. They are not intelligent in the way we are—not because they're dumb but because their behavior is the product of hundreds of millions of years of evolution under radically different conditions than the ones under which our own brains evolved.
Well, most of our brains, anyway.
