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[edit]

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


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.


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