Truly splendid! I'd heard about crows and badgers being able to use tools, but an invertebrate? Well, I always knew my ex-boss could wield an axe, so maybe tool use in invertebrates isn't all that uncommon. But this example is rather splendid: an octopus with a coconut shell. The above links to a video. I watched it about 3 times, all the time thinking: how cool is that?
