Many sea stars harbor various commensals that de- rive their food from scraps of their host’s meals. One well known relationship is that of a polynoid scale worm, Arctonoe vittata, and several species of asteroid hosts, including the Pacific leather star, Dermasterias im- bricata. The worm is an obligate symbiont, spending most of its life cruising and feeding in the host’s ambu- lacral grooves download.

The carapace may extend over the body dorsally and laterally as well as posteriorly, and it often fuses to one or more thoracic segments, thereby producing a cephalothorax (Figure 16.2A). Occasionally, the carapace may grow forward beyond the head as a narrow rostrum. Most of the differences among the major groups of crustaceans, and the basis for much of their classifica- tion, arise from variations in the number of somites in the thorax and abdomen, the form of their appendages, and the size and shape of the carapace

When threatened, these cucumbers aim the anus at the poten- tial predator, contract the body wall, and discharge the tubules by rupturing the hindgut. The tubules are shot onto the predator, entangling it in the sticky mass. The Cuvierian tubules are regenerated along with any other tissue lost during discharge.
