Burrowing, vermiform (wormlike) mollusks in the group Aplacophora. Chaetodermomorpha (also known as Caudofoveata) are covered by a cuticular integument bearing sclerites (spicules) and are recognizable by the presence of a sensory cuticular oral shield, lack of a foot, and presence of paired gills in a posterior mantle cavity. Chaetoderms (see illustration) range in size from less than 0.08 in. (2 mm) to more than 2.8 in. (70 mm) and are found from shelf depths to hadal depths over 23,100 ft (7000 m). There are four families with 14 genera and 128 species worldwide. Chaetoderm species are numerically dominant in certain deep-sea localities. See also: Deep-sea fauna
