| 説明 | Tellina lineata Turton, 1819 - rose petal tellin clam in Florida, USA. (December 2012)Bivalves are bilaterally symmetrical molluscs having two calcareous, asymmetrical shells (valves) - they include the clams, oysters, and scallops. In most bivalves, the two shells are mirror images of each other (the major exception is the oysters). They occur in marine, estuarine, and freshwater environments. Bivalves are also known as pelecypods and lamellibranchiates.Bivalves are sessile, benthic organisms - they occur on or below substrates. Most of them are filter-feeders, using siphons to bring in water, filter the water for tiny particles of food, then expel the used water. The majority of bivalves are infaunal - they burrow into unlithified sediments. In hard substrate environments, some forms make borings, in which the bivalve lives. Some groups are hard substrate encrusters, using a mineral cement to attach to rocks, shells, or wood.The fossil record of bivalves is Cambrian to Recent. They are especially common in the post-Paleozoic fossil record.The attractive pinkish-reddish shell shown above is a right valve from a rose petal tellin clam, Tellina lineata - also known as Eurytellina lineata. This species is a soft substrate infaunal filter feeder.Classification: Animalia, Mollusca, Bivalvia, Heterodonta, Veneroida, TellinidaeLocality: Bird Key Middle Ground East Beach (Main Channel North Beach; Cabbage Key-Pine Key North Beach) - marine shoreline on the eastern side of Rt. 679, just north of Cabbage Key & Pine Key, northern side of Tampa Bay, south of the city of St. Petersburg, Gulf of Mexico coast of southern Florida, USA |
