Line 2: Line 2:
'''Characters''' (from Cox ''et al.'' 1969): Closed mantle and truncate, more or less circular foot developed as suction disc. Shells inequilateral, dorsal margin reflected anterior to beak, forming attachment area for anterior adductor muscle which works counter to posterior adductor when animal is boring. Hinge teeth lacking, but small chondrophore and internal ligament usually present. Ventral adductor muscle or at least thickening of muscles of ventral margin of mantle located at union of anterior slope and disc, forming pivotal point opposite umbones on which valves rock when boring. Gills usually elongate, with two demibranchs except in Xylophagainae and Teredinidae. Apophyses found in all Pholadacea except in some Pholadidae.
