Annelids: Worms and Leeches


Annelids have bodies that are divided into segments. Annelids have very well-developed internal organs.

Some may have long bristles. Others have shorter bristles and seem smooth, like the earthworm shown here.

There are about 9,000 species of Annelids known today, including worms and leeches.
