Kinosternon

Kinosternon is a genus of small aquatic turtles from the Americas known commonly as mud turtles.

Geographic range
They are found in the United States, Mexico, Central America, and South America. The greatest species richness is in Mexico, and only three species (K. dunni, K. leucostomum, and K. scorpioides) are found in South America.

Description
They are very similar to the musk turtles, but generally smaller in size, and their carapaces are not as highly domed.

Diet
All mud turtles are carnivorous, consuming various aquatic invertebrates (especially molluscs and worms ), fish, and even carrion.

Behavior
Mud turtles live in the ground layer on the bed of bodies of slowly-flowing or still water. By burrowing deeply into mud, mud turtles are protected from danger. They occasionally like to bask in the sun.
