Bryozoan colonies don't really look like animals – they look a little like little trees or flowers or something – but when you actually look at the level of the individual, they do look like an animal. They are a little worm with a nose that has tentacles around the outside, and they sit inside their little box, and when they think it’s a good idea, they open the door and poke their tentacles out and catch something. So they aren't particularly different from other animals you know. They’re just really, really small, and the colonies they make by gluing together look a little like plants.
