Then annelids are broken down into 3 major classes. I belong to the class Oligochaeti and there are about 3,100 of us. As you can see, a class is smaller than a phylum (there were 9,000 of us in the phylum).

So what makes us different from the rest of the classes? Well, we Oligochaeti have fewer setae (hairs or bristles) on our segments and our bodies are really made for burrowing and digging. We don't have any eyes or feelers.

The name Oligochaeti means "few hairs."
