Bristle Worms - Polychaete.
http://www.chesapeakebay.net/polychaete.htm
Polychaetes ('many hairs') belong to a phylum of cylindrical soft-bodied invertebrates, Annelida, which date from the Paleozoic era. An annelid's body structure consists of a fluid-filled 'tube-within-a-tube', or coelum, with a projection that resembles a head at one end.
