The Big Bend slider (Trachemys gaigeae), also called the Mexican Plateau slider, is a species of aquatic turtle in the family Emydidae. The species is endemic to the Southwestern United States and northern Mexico.
T. gaigeae is native to the United States in the states of New Mexico and Texas, and to northern Mexico in the state of Chihuahua. It is found primarily in the Rio Grande, Rio Concho, and Rio Nazas river systems.
The species Trachemys gaigeae was first described by professor of zoology at the University of Michigan, Dr. Norman Edouard Hartweg, in 1939, as a subspecies, Pseudemys scripta gaigeae. Later, it was assigned to the genus Chrysemys, then to the genus Trachemys. Most recently, it was granted full species status, though many sources still refer to it by its various synonyms.
Primarily aquatic, the Big Bend slider is often seen basking on rocks or logs in the water, and when approached quickly dives to the bottom. The only time it spends a large amount of time on land is when females emerge to lay eggs. It is an omnivorous species, with younger animals being more carnivorous, and progressively becoming more herbivorous as they age, with older adults being nearly entirely herbivorous.
Adults of T. gaigeae have a straight carapace length of 5 to 11 inches (13 to 28 cm).
