Description

Terrapins are four to ten inches long, with a bluish gray or black shell that has diamond shaped scutes. Sometimes black stripes or spots may be visible on the scutes and skin. Their plastron is orange with black splotches, and they have lighter skin. Females are larger than males.

Habitat

These turtles live in estuaries and brackish water, either in salt marshes or coastal habitats. 

Behavior

These highly aquatic turtles have skin that is impermeable to salt, allowing them to tolerate brackish waters. They eat fish, invertebrates, and algae. They are docile, but may bite if cornered and threatened. They lay around ten eggs in June on slopes facing marshes.
