. . . Cuttlefish. I love cuttlefish. This is a giant Australian cuttlefish. And there he is, his droopy little eyes up here. But they can do pretty amazing things, too. Here we’re going to see one backing into a crevice, and watch his tentacles—he just pulls them in, makes them look just like algae. Disappears right into the background. Positively amazing. Here’s two males fighting. Once again, they’re smart enough, these cephalopods; they know not to hurt each other. But look at the patterns that they can do with their skin. That’s an amazing thing.
