Pyganodon cataracta, formerly Anodonta cataracta, is a species of large freshwater mussel, an aquatic bivalve mollusc in the family Unionidae, the river mussels. Its common name is the eastern floater.

Subspecies

  • Pyganodon cataracta subsp. cataracta
  • Pyganodon cataracta subsp. marginata

Description

[edit]

Pyganodon cataracta can reach a size of 10–15 centimetres (3.9–5.9 in).

Distribution and habitat

[edit]

This mussel is present in freshwater habitats along the Atlantic coast of North America, ranging from Alabama to some parts of Canada. It is typically found in soft-bottomed ponds, rivers and small lakes.

Taxonomy

[edit]

Like many other of its relatives, the eastern floater was thought to be in the genus Anodonta, but was since moved to other genera such as Pyganodon, Utterbackia, and more.[3]
