Overview
A musk turtle with a distinct, sharp keel running along the midline of its shell, giving a razor-backed profile, and a tan or grey shell with dark mottling. It is highly aquatic in rivers and streams of the south-central US and feeds heavily on snails and mussels.
Classification
The Razor-backed Musk Turtle belongs to the suborder Cryptodira (hidden-neck turtles) and the family Kinosternidae. It is a family of small, mostly American freshwater turtles known for the musky odour they release when disturbed. Its scientific name is Sternotherus carinatus.
Appearance & Distinguishing Features
They are small with a reduced, often cross-shaped plastron that leaves the limbs exposed, a short head, and a pair of barbels on the chin. Many have a smooth, dark shell.
Habitat & Distribution
They inhabit slow streams, ponds, marshes, and temporary wetlands from southern Canada through much of the Americas.
Diet & Feeding
They are omnivorous, feeding on invertebrates, small fish, amphibians, and plant matter, often foraging on the bottom.
Behavior & Conservation
When threatened they emit a pungent musk from glands at the shell edge. Several small species are kept as manageable pet turtles.
Popularity & Recognition
Their small size makes them popular beginner turtles, though their musk defence is legendary among keepers.
