What are the razorback musk turtles look like?

Razorback musk turtles (Sternotherus CARINATUS) are small freshwater turtles characterized by their distinctive, raised keel running along their shells, giving them a "razorback" appearance. They have dark, often olive or brownish shells with a slightly domed shape, and their skin is typically gray or brown. These turtles also possess a small head with prominent, yellow or white stripes on the sides, and they have a strong, musky odor when threatened. Their size is relatively small, usually ranging from 4 to 5 inches in shell length.
