Lampsilis Abrupta
''Lampsilis abrupta'', the pink mucket or pink mucket pearly mussel, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species is endemic to the United States. Life history The pink mucket is a rounded, slightly elongated mussel with a thick, inflated, and smooth shell, which is usually yellow-brown in color.*Bessken, Charlene M. “Pink Mucket- Lampsilis abrupta.” Missouri Department of Conservation. Conservation Commission of Missouri. Web. 12 Oct. 2009. It can be found on the bottoms of various bodies of water, among gravel and cobble. It can be found in water one inch to five feet in depth.*“Best Management Practices.” Missouri Department of Conservation. N.p. Web. 19 Oct.2009. The mussel can live up to fifty years, but it rarely reaches this age now. The pink mucket has been a federally endangered species since the year 1976. The pink mucket reproduces in a similar manner to most other freshwater mussels. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and Herpetology, herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Religious Society of Friends, Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram.

Kentucky
Kentucky ( , ), officially the Commonwealth of Kentucky, is a state in the Southeastern region of the United States and one of the states of the Upper South. It borders Illinois, Indiana, and Ohio to the north; West Virginia and Virginia to the east; Tennessee to the south; and Missouri to the west. Its northern border is defined by the Ohio River. Its capital is Frankfort, and its two largest cities are Louisville and Lexington. Its population was approximately 4.5 million in 2020. Kentucky was admitted into the Union as the 15th state on June 1, 1792, splitting from Virginia in the process. It is known as the "Bluegrass State", a nickname based on Kentucky bluegrass, a species of green grass found in many of its pastures, which has supported the thoroughbred horse industry in the center of the state. Historically, it was known for excellent farming conditions for this reason and the development of large tobacco plantations akin to those in Virginia and North Carolina i ...

Bivalves Described In 1831
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 calc ...

Lampsilis
''Lampsilis'' is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. There are over 100 species in the genus. Some species, notably ''Lampsilis ovata'' (pocketbook mussel) use aggressive mimicry to lure large predatory fish by using their mantle as a lure, ejecting larvae into the mouth of the fish when they strike. The larvae attach to the gills, using the fish's blood as food for several weeks. Species * '' Lampsilis abrupta'' (pink mucket) * '' Lampsilis binominata'' (lined pocketbook) * '' Lampsilis bracteata'' * '' Lampsilis cardium'' * '' Lampsilis cariosa'' (yellow lampmussel) * '' Lampsilis dolabraeformis'' * ''Lampsilis fasciola'' (wavy-rayed lampmussel) * '' Lampsilis floridensis'' (Florida sandshell) * '' Lampsilis fullerkati'' (Waccamaw fatmucket) * '' Lampsilis higginsii'' (Higgins' eye pearly mussel) * '' Lampsilis ornata'' * ''Lampsilis ovata'' (pocketbook mussel) * '' Lampsilis powellii'' (Arkansas fatmucket) * '' ...

Molluscs Of The United States
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant taxon, extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater mollusc, freshwater and Terrestrial molluscs, terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 Taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologically advanced of all inve ...
