Codakia distinguenda, the elegant lucine, is a species of marine bivalve mollusc. [3] It was first described to science in 1872 by George Washington Tryon Jr. [2]
The elegant lucine has large, flattened, saucer-like valves. They are the largest member of their family along the west coast of the Americas. The valves are between 50mm and 140mm (2 to 5.5 inches) in width. The exterior of the shell is white with a vivid reticulation, or net-like sculpture of rays and arcs. The interior of the shell shows rose-red margins with a creamy yellow center. [4]
The elegant lucine is found in the east Pacific Ocean from Baja California to Peru, including the Gulf of California. [4] It is found in the Galapagos Islands. [5] It is a shallow water species that lives from the intertidal zone to 50 meters (165 feet) deep. Elegant lucinids are infaunal, that is, they live buried in sand or mud on the seabed. [1] [6]
The elegant lucine is a filter feeder, straining plankton and other nutrients from sea water that it pumps through its body. [7] These animals also obtain energy through chemosymbiosis. [1] They acquire their symbiotic bacteria from sea water. The bacteria are bathed in the sea water pumping through the gills of the animal from which they obtain sulfides and oxygen. The bacteria use these inputs to synthesize nutritious carbon compounds that are transferred to the lucine. In times of starvation, the lucine will consume the bacteria. [8]
The shipworms are marine bivalve molluscs in the family Teredinidae: a group of saltwater clams with long, soft, naked bodies. They are notorious for boring into wood that is immersed in sea water, including such structures as wooden piers, docks and ships; they drill passages by means of a pair of very small shells (“valves”) borne at one end, with which they rasp their way through. They are sometimes called "termites of the sea". Carl Linnaeus assigned the common name Teredo to the best-known genus of shipworms in the 10th edition of his taxonomic magnum opus, Systema Naturæ (1758).
Bivalvia, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. The class includes the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances.
Lucinidae, common name hatchet shells, is a family of saltwater clams, marine bivalve molluscs.
Lienardia rigida is a species of sea snail, a marine gastropod mollusk in the family Clathurellidae.
Lucina pensylvanica, commonly known as the Pennsylvania lucine, is a species of bivalve mollusc in the family Lucinidae.
Anodontia alba, or the buttercup lucine, is a species of bivalve mollusc in the family Lucinidae. It can be found along the Atlantic coast of North America, its range extending from North Carolina in the United States to the West Indies.
Anodontia philippiana, or the chalky buttercup, is a species of bivalve mollusc in the family Lucinidae. It can be found burrowing in soft substrate in shallow waters along the Atlantic coast of North America, its range extending from North Carolina in the United States to the West Indies and Bermuda.
Codakia orbicularis, or the tiger lucine, is a species of bivalve mollusc in the family Lucinidae. It can be found along the Atlantic coast of North America, ranging from Florida to the West Indies.
Ctena orbiculata, commonly known as the dwarf tiger lucine, is a species of bivalve mollusc in the family Lucinidae. It can be found along the Atlantic coast of North America, ranging from North Carolina to the West Indies.
Divaricella quadrisulcata, or the cross-hatched lucine, is a species of marine bivalve mollusc in the family Lucinidae. D. quadrisulcata, also known as Divalinga quadrisulcata, are known for their unique shell patterns. The shells of D. quadrisulcata have been used as jewelry and can be collected along the shore in many Atlantic coastal states in North America. These organisms are known to have a symbiotic relationship with sulfur-oxidizing bacteria, as is characteristic of many other organisms within the family Lucinidae.
