Girdle relatively narrow, occupying less than half of the total width, bearing short corneous bristles or overlapping calcareous scales. Outer surface of the shell variously sculptured, rarely smoothish. Lateral areas of intermediate valves usually well marked. All valves with short insertion plates, which are usually incised by slits, but not pectinate on their outer margin; insertion plate of the head valve with 6 or more slits. Sutural plates well developed on intermediate and tail valves. Slow-moving animals, common on rocks or under stones of the intertidal and shallow subtidal zones, grazing on algae, diatoms, hydroids, bryozoa, or even small barnacles. Locally collected by coastal people, for human consumption or for baiting (Ref. 104052). |
