Obovaria Retusa
''Obovaria retusa'' is a rare species of freshwater mussel in the family Unionidae, the river mussels. Its common names include golf stick pearly mussel This mussel was native to Alabama, Illinois, Indiana, Kentucky, Ohio, Pennsylvania, Tennessee, and West Virginia. By 1991 it was thought that there were about five populations remaining in Kentucky, Tennessee, and West Virginia. It is now thought to be extirpated from West Virginia, as the population there was a misidentification. Only a few specimens of the species have been observed recently. If any viable populations remain, they will be located in the Green River of Kentucky. General Summary The Ring Pink mussel (Obovaria retusa) is also referred to as the “golf stick pearly mussel” or “Ring Pink.”Biggins, Richard G. “Ring Pink Mussel Recovery Plan.” Ecos.fws.gov, U.S. Fish and Wildlife Service, 25 Mar. 1991, https://ecos.fws.gov/docs/recovery_plan/910325.pdf.

Obovaria Arkansasensis
''Obovaria arkansasensis'', the Ouachita creekshell, is a species of freshwater mussel, an aquatic bivalve mollusc in the family Unionidae, the river mussels. It is endemic to certain rivers and streams in the Ouachita Mountains, Arkansas, and has a complex life history including its larvae being parasitic on a fish host. Description The Ouachita creekshell grows to about in length. The shell is thin but has robust hinge teeth, especially at the anterior end. There are sometimes a few fine ribs on the posterior end of the shell. The periostracum is olive or yellowish-brown. This species is dimorphic with the males being ovate and the females being less compressed laterally and with the posterior end truncated and sometimes with a notch on the posterior margin. ''Obovaria arkansasensis'' shows great similarity in general appearance to '' Obovaria jacksoniana''. However, its shell morphology and life cycle are different, as are the species of host fish with which it is assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unionidae
The Unionidae are a family of freshwater mussels, the largest in the order Unionida, the bivalve molluscs sometimes known as river mussels, or simply as unionids. The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks. Origin and early diversification The recent phylogenetic study reveals that the Unionidae most likely originated in Southeast and East Asia in the Jurassic, with the earliest expansions into North America and Africa (since the mid-Cretaceous) followed by the colonization of Europe and India (since the Paleocene). Life history Unionidae burrow into the substrate, with their posterior margins exposed. They pump water through the incurrent aperture, obtaining oxygen and food. They remove ...

Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Bivalve Genera
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. They include 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. The shell of a bivalve is composed of calcium ...

Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine. Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded the Muséum ...
