Segmented worms

Many different animals with long round soft bodies and no legs are called worms. The simple bodies of these marine worms are divided into segments.

There are different kinds of segmented worms living in the sea. Like earthworms, all segmented worms have round bodies divided into segments. 

They don’t have legs. They can have rows of bristles growing from their body. The bristles can be large or can only be seen using a microscope. Segmented worms can tell the difference between light and dark, but they don’t have eyes so they cannot see. 

Some segmented worms make and live inside protective tubes for their entire lives. Others move about freely.
