The Texas map turtle (Graptemys versa) is a species of emydid turtle endemic to the southern United States. Texas map turtles are popular in the pet trade. However, they became more common because of captive breeding.

Geographic range

It is found in central Texas in the Colorado River drainage on the Edwards Plateau.

Description

Graptemys versa is a smaller map turtle; females only attain a carapace length of 12.5 cm (5.0 in).[3] Males are even smaller, only attaining a carapace length of 9.0 cm (3.5 in).[4] The keel on this map turtle is not black, and a J-shaped head marking is seen.

Diet

They feed mainly on mollusks, insects, carrion, and vegetation.
