Polychaete Worm Nephtys californiensis |

|
You can see that this Polychaete Worm is related to earthworms, because its body is segmented (it has sections) like earthworms. But its body also has bristles coming out of each segment, so this group of worms is called "bristle worm." The polychaete’s head looks different from the rest of its body. That’s another way it is different from an earthworm. It is preyed upon by crabs, other polychaete worms, and fish.
