The Alabama spike is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
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 drainages within the Chipola River. The federal Endangered Species Act protects it as a designated threatened species by Florida's Endangered and Threatened Species Rule.

Elliptio downiei is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
Elliptio folliculata is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
The brother spike is a species of freshwater mussel the family Unionidae, the river mussels. This species is endemic to the Savannah River, United States. It listed as "endangered "in 1996 and was changed due to insufficient information and it has a world listing of "critically imperilled/imperilled".

Elliptio producta, also known as the Atlantic spike, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species is endemic to the Eastern United States. It occurs on the Atlantic coast between the Savannah River and the Roanoke River basin. It may have been extirpated from the Ogeechee River system in Georgia. It lives in medium to large rivers on sand and gravel substrate.
Elliptio shepardiana,, the Altamaha lance, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels, naiads or unionids.
Elliptio spinosa, the Altamaha spinymussel, is an endangered species of freshwater mussel in the family Unionidae. They live in southeastern Georgia in the Altamaha river and its tributaries. It is one of three species of North American spinymussels which are recognizable by their prominent spines. The Altamaha spinymussel genetically diverged from the other spinymussels 3.76 million years ago. This suggests that their spines evolved separately from the spines of other North American spinymussels. The Altamaha spinymussel is on the Endangered Species Act because of many threats with the most prominent threats being habitat loss, decrease in water quality, shrinking range, small population size, and vulnerability to disturbances.
The James River spinymussel, also known as the Virginia spinymussel, is a species of freshwater mussel in the family Unionidae, the river mussels. This species is native to North Carolina, Virginia, and West Virginia in the United States. It is a federally listed endangered species of the United States. It was formerly placed in Pleurobema but in 2017, Perkins, Johnson & Gangloff placed the species into a new genus Parvaspina on account of genetic data and its lateral spines.
The eastern elliptio is a freshwater mussel in the Unionidae family, native to Canada and the United States. It is a bivalve member of the phylum Mollusca. Not only is it found in Canada and the United States, but it is frequently the most abundant species of mussel found in its home waterways. It is the most common mussel in the Delaware River and the most common mussel found in the state of New Hampshire and Vermont. It can be found in the substrate at the bottom of lakes, ponds and rivers. Size is variable, but can reach up to 13 centimetres (5.1 in) in length.
