As the name suggests, bivalves are enclosed in a pair of shells (or valves) that are hinged at the dorsal side. Plenty of less-common bivalves exist as well, and some are eaten in smaller numbers where they are plentiful enough to catch, cook and consume. 53. Assess anatomical vocabulary comprehension with the Clam Anatomy Labeling Page. There is generally a muscular foot, which may be used for walking. Physical Traits: They have two shells connected by a hinge called the ligament, and kept closed by powerful muscles. Members of class Scaphopoda (boat feet) are known colloquially as tusk shells or tooth shells, as evident when examining Dentalium, one of the few remaining scaphopod genera. The word "gastropod" means "stomach foot" because most of them have their Diet: Unlike many mollusks that feed using a rasping tongue, called a radula, bivalves feed by filtering food particles from the water. Molluscs - ScienceDirect Most gastropods bear a head with tentacles, eyes, and a style. The radula is a feeding organ with teeth made of chitin. Most chiton species inhabit intertidal or subtidal zones, and do not extend beyond the photic zone. Each one is different from the adult stage. Only the phylum Arthropoda . Gastropods General - snails, limpits, nudibranchs, slugs The largest class of mollusc - over 40 thousand living species Class Aplacophora includes worm-like animals with no shell and a rudimentary body structure. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. 2. Physical Traits: They have a large, muscular foot on which they move slowly along any surface and the visceral mass sits atop the foot. Mollusks are invertebrates and include octopus, squid, snails, slugs, clams, and oysters and many others. There are over 100,000 different mollusks, so there are bound to be some interesting looking organisms, like this one. Squid and octopuses have a funnel structure, called a hyponome, through which they can blow water to move themselves quickly along.
