Quadrula Cylindrica Strigillata
''Quadrula'' is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae native to rivers of the American Midwest and mid-south.

Quadrula Fragosa
The winged mapleleaf, also known as false mapleleaf, or hickory nut shell, and with the scientific name ''Quadrula fragosa'', is a species of freshwater mussel. It is an aquatic bivalve mollusk in the family Unionidae, the river mussels. It is endemic to the United States. ''Quadrula fragosa'' is only located in a few parts of Wisconsin, Minnesota, Arkansas, and Missouri — in the Midwestern United States. It is a federal critically endangered river mussel species. Description The anterior end of the ''Quadrula fragosa'' shell is slightly rounded and the posterior end of the shell is more of a square shape. The shell can range in color from a yellowish-green to light or dark brown. The inside of the shell is white, and there is sometimes iridescent coloring at one end of the shell. The diameter of a mature mussel of this species is usually about 4 inches (10.2 cm). The shells of these mussels are very thick, and unlike many other mussels, there are bumps on the shell ...

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 ...

Quadrula Quadrula
''Quadrula quadrula'', the mapleleaf, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. The thick shell is about as broad as it is long with heavy hinge teeth. The outside may be yellowish green to dark brown and the inside is white. Two rows of raised bumps extend in a v-shape from the umbo to the back edge in most individuals. This species is native to North America. In the United States, it is found in the Interior, Nelson and Great Lakes basins, as well as in the western Gulf Coastal Plain. Two populations occur in Canada, one found in Manitoba in the Red River, the Assiniboine River, and Lake Winnipeg and the other in Ontario in rivers emptying into Lake Huron, Lake Erie, Lake St. Clair, and Lake Ontario. The population in Manitoba is designated 'Threatened' by the Committee on the Status of Endangered Wildlife in Canada. while the Ontario population is designated of 'Special Concern.'

Freshwater Mussel
Freshwater bivalves are one kind of freshwater mollusc, along with freshwater snails. They are bivalves that live in fresh water as opposed to salt water, which is the main habitat type for bivalves. The majority of species of bivalve molluscs live in the sea, but in addition, a number of different families live in fresh water (and in some cases, also in brackish water). These families belong to two different evolutionary lineages (freshwater mussels and freshwater clams), and the two groups are not closely related. Freshwater bivalves have a simple morphology that varies among taxa, and are distributed around most regions of the world. Species in the two groups vary greatly in size. Some pea clams (''Pisidium'' species) have an adult size of only 3 mm. In contrast, one of the largest species of freshwater bivalves is the swan mussel, in the family Unionidae; it can grow to a length of 20 cm, and usually lives in lakes or slow rivers.
