Obovaria unicolor is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This mussel has a round or elliptical shape.
This species is endemic to the United States.
Mussel is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval.
The Green River is a 384-mile-long (618 km) tributary of the Ohio River that rises in Lincoln County in south-central Kentucky. Tributaries of the Green River include the Barren River, the Nolin River, the Pond River and the Rough River. The river was named after Nathanael Greene, a general of the American Revolutionary War.
The zebra mussel is a small freshwater mussel. The species was originally native to the lakes of southern Russia and Ukraine, but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River, and Lake Travis.
The Sydenham River is a river in Kent County, Lambton County and Middlesex County in southwestern Ontario, Canada, flowing southwest from its source west of London, Ontario and emptying into Lake Saint Clair. The length of the river is 165 kilometres (103 mi) and it drains a watershed of approximately 2,700 square kilometres (1,000 sq mi). The river flows through the towns of Strathroy and Wallaceburg. It was named after Lord Sydenham, governor of Canada from 1839 to 1841.
The blue mussel, also known as the common mussel, is a medium-sized edible marine bivalve mollusc in the family Mytilidae, the mussels. Blue mussels are subject to commercial use and intensive aquaculture. A species with a large range, empty shells are commonly found on beaches around the world.
Tide pools or rock pools are shallow pools of seawater that form on the rocky intertidal shore. Many of these pools exist as separate bodies of water only at low tide.
The shovelnose sturgeon is the smallest species of freshwater sturgeon native to North America. It is often called "hackleback", "sand sturgeon", or "switchtail." Switchtail refers to the long filament found on the upper lobe of the caudal fin. Shovelnose sturgeon are the most abundant sturgeon, found in the Missouri River and Mississippi River systems, and the only commercially fished sturgeon in the United States of America.
The brown lanternshark or bristled lanternshark is a little-known species of deep-sea dogfish shark in the family Etmopteridae. It is found off Japan and New Zealand, and possibly also South Africa and Australia, typically deeper than 300 m (980 ft). This species can be distinguished from other lanternsharks by its coloration, which is a uniform dark gray or brown without the ventral surface being much darker and clearly delineated from the rest of the body. The brown lanternshark feeds on small bony fishes, cephalopods, and crustaceans. Reproduction is ovoviviparous, with females giving birth to 9–18 young. An unusually high proportion of individuals in Suruga Bay are hermaphrodites, with both male and female characteristics.
Unionida is a monophyletic order of freshwater mussels, aquatic bivalve molluscs. The order includes most of the larger freshwater mussels, including the freshwater pearl mussels. The most common families are the Unionidae and the Margaritiferidae. All have in common a larval stage that is temporarily parasitic on fish, nacreous shells, high in organic matter, that may crack upon drying out, and siphons too short to permit the animal to live deeply buried in sediment.
Obovaria jacksoniana is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
Obovaria is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. There are at least six described species in Obovaria at present, all of which are found in the United States. Obovaria subrotunda is found in Canada as well.
Obovaria olivaria is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
Obovaria retusa is a rare species of freshwater mussel in the family Unionidae, the river mussels. Its common names include golf stick pearly mussel and ring pink. It is native to parts of the eastern and southeastern United States, but it remains in very little of its original range. There may be no viable populations left. This is a federally listed endangered species of the United States.
Obovaria subrotunda, common name the round hickorynut, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
Byturidae, also known as Fruitworms, is a very small family of beetles, in the suborder Polyphaga, comprising fewer than 20 species worldwide. The larvae of some species develop in fruits. Byturus unicolor affects species of Rubus and Geum.
Villosa 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.
Obovaria haddletoni 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.
The Nore pearl mussel is a critically endangered species of freshwater pearl mussel, an aquatic bivalve mollusc in the family Margaritiferidae.
