Here’s another pretty little character. This is a tiny squat lobster, perhaps a half inch in length or so, that lives on a barrel sponge. I’ve heard these called Hairy Crabs, Fairy Crabs and even Sid Vicious crabs :). They camoflauge very well against the sponge, despite their vivid pink and purple coloration. But when you put a little light on them, they almost sparkle.
