The Ouachita map turtle or Sabine map turtle (Graptemys ouachitensis) is a species of turtle endemic to the United States.

Description[edit]

This species’ carapace features a row of low vertebral spines, and is serrated on the posterior rim. The carapace is olive, dark brown, or black in coloration with light yellowish markings with dark borders. The plastron color varies from cream to yellow and is patterned with dark lines and swirls. The body color is grayish brown to blackish and is marked with yellowish stripes.

Males are significantly smaller than females. The males can grow to be as large as 5 inches (12.5 cm) in carapace length. The females can grow to be up to 10 inches (25.5 cm) in carapace length.

Taxonomy[edit]

The subspecies may represent full species.[2]

Diet[edit]

Ouachita map turtles feed mainly on small aquatic animals such as shrimp, insects, molluscs, and fish. They also consume algae and aquatic plants.

Pet trade[edit]

As they are small, Ouachita map turtles are common amongst turtle keepers. They can be kept with most other species and can be raised on specialty pellets and dried shrimp. Although they need heat and UVB, they can generally be kept in average-sized aquariums.
