Description

The narrow-bridged musk turtle is typically brown in color. The scutes of the carapace have lines and graining, imparting an almost wood-like appearance. It often has bright-yellow markings on the edges of the carapace. As it ages, algae often heavily cover the shell, masking the patterning and coloration. The head is large and bulbous for its size, with a sharp beak and a long neck. The carapace is domed, with three distinct ridges down the length. Though classified in the subfamily Staurotypinae with the "giant" musk turtles, the narrow-bridged musk turtle generally only grows to a straight carapace length of about 6.5 in.

Behavior, habitat, and diet

Like all musk turtles, the narrow-bridged musk turtle is almost entirely aquatic, and prefers habitats such as slow-moving creeks, or shallow ponds that are heavily vegetated. It spends much of its time walking along the bottom, foraging for aquatic insects and other invertebrates, and carrion. It has glands under the rear of the shell from which it can release a foul-smelling musk, hence its common name.
