Sternotherus is a genus of aquatic turtles known commonly as musk turtles, which are endemic to North America. This genus is closely related to the genus Kinosternon.[2] The most common species of Sternotherus in most of North America is Sternotherus odoratus, the common musk turtle or stinkpot; that entry has more information on the ecology of this group of turtles.

Geographic range[edit]

The genus occurs in southern Canada, as well as the United States and Mexico.

Description[edit]

They are very similar to the American mud turtles, but tend to have a more domed carapace, with a distinctive keel down the center of it. Sternotherus odoratus typically grows to only 8–14 cm (3–5½ inches) in carapace length at full maturity, with females often being larger than males.

Diet[edit]

All musk turtles are carnivorous, consuming various aquatic invertebrates, fish, and carrion.

Behavior[edit]

They are a highly aquatic genus. But some, like the common musk turtle, are known to bask on fallen trees and coarse woody debris on shorelines.[2]
