It wasn’t planned this way, but the Talk Science logo has become a sort of test (a fun one, we hope). Pretty much everyone can identify what’s in the first circle. Far fewer can tell at a glance what the second one contains (only one person has gotten it right the first time). And I don’t think we’ve ever had anyone name the item in the third circle right away, although occasionally someone comes close.
This is, of course, a cephalopod. An octopus, to be specific. Octopuses (that is how we pluralize it here) are a nearly endless source of weird biology facts. They have three hearts and no skeleton, and their brains are widely distributed throughout their extremely compressible bodies. And they’re smart. There’s debate about precisely how smart and in what ways, but their behaviour demonstrates remarkable adaptability and complexity.
