The Texas map turtle (Graptemys versa) is a species of emydid turtle endemic to Texas.
Geographic range
[edit | edit source]Endemic to Texas within the Colorado River (Texas) drainage
Description
[edit | edit source]Graptemys versa is a smaller turtle; females only attain a carapace length of 21.4 cm (8.4 in). Males are even smaller, only attaining a carapace length of 9.0 cm (3.5 in). When viewed dorsally, the carapace is oval-shaped with the widest part just above the rear legs. The posterior marginals are serrated and the carapacial scutes are convex. A medial keel is present on the vertebral scutes with the most prominent keels being located on the first three. The apex of these scutes are yellowish but often become worn down with age. The base coloration of the carapace is olive green with yellow reticulations. Juveniles and young adults often bear some slight pattern along the central seams of the plastral scutes. However, some adults have a creamy yellow plastron free of markings.
Diet
[edit | edit source]Map turtle researcher Peter Lindeman has documented the following dietary items from Texas map turtles: Freshwater sponges, algae, seeds, Asian clams, various aquatic insects, leeches, and crayfish.
