Annelids: The clam worm is an example of a segmented worm common to the sediments of the Littoral Zone (see the photo of burrows to the right). It is a well equiped predator (protrusible jaws) and will consume animals smaller than itself. Parapodia project from each body segment and in the anterior region there are 4-5 pairs of sensory tentacles with 4 eyes (anterior cephalization). Like all annelids, the clam worm has the ability to regenerate when cut in two pieces.     Go to the next page  Return to the survey page.
