Elliptio
''Elliptio'' is a genus of medium- to large-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, commonly known as the unionids, freshwater mussels or naiads. In contrast with many other groups of American Unionidae, the ''Elliptio'' species reach their greatest diversity in the Atlantic-draining rivers of Georgia and the Carolinas, and large parts of Florida. One species ranges north into New England and southern Canada, and two occur in the interior Mississippi drainages. Most ''Elliptio'' species have elongated shells, with silvery or purplish interior nacre beneath a thick periostracum, and few reach large size or thickness. The genus name ''Elliptio'' refers to the elliptical shape of these bivalves. As of 2003 there are 36 species in the genus.

Elliptio Crassidens
''Elliptio crassidens'', the elephant-ear, is a species of freshwater mussel, an aquatic bivalve mollusk in Unionidae, the river-mussel family. The elephant-ear possesses a thick triangular shell which may be up to six inches long. The outside of the shells is brown or black while the inside is typically light purple. It usually is found in the mud, sand, or fine gravel of large rivers. This mussel is found in the midwestern, eastern, and some southern states of the United States as well as the provinces of Quebec and Ontario in Canada. Elephant-ears typically breed once a year. Breeding seasons are short, lasting from either April through May or June to July. Both males and females reach sexual maturity at four to six years. Larvae stay in their mother's gills anywhere from a few weeks to a few months. Eventually, the offspring will attach to a host fish's fins or gills. After living parasitically on the host fish for several weeks, juvenile clams break free and fall to bottom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The larger Tar River spinymussels don’t grow larger than roughly 5.5 cm (2.2 in). Life History The female spinymussels’ time of gravidity runs from early April to mid-July. At the end of the gravid period the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elliptio Chipolaensis
The Chipola Slabshell is a part of the phylum: Mollusca and the class: Bivalvia. This species has suffered a large decrease with upwards of 75% of habitat lost. It is now confined to only a few remnant sites in small drainage from the Chipola river. The federal ESA protects it as a designated threatened species by Florida’s Endangered and Threatened Species Rule. Description The Chipola Slabshell is a freshwater mussel that is oval shaped with a reddish-brown outer shell. They can have dark and light bands on the outer shell and the inside of the shell is reddish-yellow. They can reach a length of up to 8.5 cm (3.3 in). There is no sexual dimorphism shown in the characteristic of the shells. Life History Currently, there is little information known about their complete life history. However, current beliefs suggest that males release sperm in the water and the female collects it via a siphon. Then, the eggs are fertilized in the shell of the female before the larvae are rel ...
