Palaeotaxodonta
Protobranchia is a subclass (biology), subclass of bivalve molluscs. It contains the extant order (biology), orders Nuculanida, Nuculida, and Solemyida. These are deep water clams of a small and primitive order with a taxodont hinge (composed of many similar, small teeth), generally with a central ligament pit, large labial palps which are used in deposit feeding and the Gill#Invertebrates, gills used only for respiration, the anterior and posterior Adductor muscles (bivalve), adductor muscles are nearly equal in size, a foot which is divided sagittally and longitudinally with papillate margins. The foot (mollusc), foot in Protobranchia clams is without a true byssus gland, although they frequently have a analogous organ, nonhomologous byssal gland in the heel. The byssal gland in these clams does not produce threads as in Pteriomorphia. 2010 Taxonomy In 2010 a new proposed classification system for the Bivalvia was published by Bieler, Carter & Coan revising the classificati ...

Bivalve
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class (biology), class of aquatic animal, aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-bivalve shell, shells known as valve (mollusc), valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Common bivalves include clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. Majority of the class are benthic filter feeders that bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valve (mollusc)
A valve is each articulating part of the shell of a Mollusca, mollusc or another multi-shelled animal such as Brachiopod, brachiopods and some Crustacean, crustaceans. Each part is known as a valve or in the case of Chiton, chitons, a "plate". Members of two Class (biology), classes of molluscs, the Bivalvia (clams) and the Polyplacophora (chitons), have valves. Species within one family of very unusual small sea snails, marine (ocean), marine opisthobranch gastropods in the family Juliidae, also have two articulating shells or valves, which resemble those of a bivalve. This exceptional family is commonly known as the bivalved gastropods. Gastropods in general are sometimes called "univalves", because in those that have a shell, the shell is usually in one part. Chitons The valves of chitons are eight dorsum (biology), dorsal, wiktionary:articulated, articulated shell plates, which are frequently coloured and sculpted. After death the girdle that holds the plates together disin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
