Sternotherus is a genus of aquatic turtles, known commonly as musk turtles, in the family Kinosternidae. The genus is 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
The genus Sternotherus occurs in southern Canada, as well as the United States and Mexico.
Description
Turtles in the genus Sternotherus are very similar to the American mud turtles in the genus Kinosternon, 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 (3.1–5.5 in) in straight carapace length at full maturity, with females often being larger than males.
Diet
All musk turtles are carnivorous, consuming various aquatic invertebrates, fish, and carrion.
Behavior
Sternotherus is a highly aquatic genus. But some species, like the common musk turtle, are known to bask on fallen trees and coarse woody debris on shorelines.[2]
