The Big Bend slider (Trachemys gaigeae), also called commonly the Mexican Plateau slider and la jicotea de la meseta mexicana in Mexican Spanish, is a species of aquatic turtle in the family Emydidae.

[6] The epithet, gaigeae, is in honor of American herpetologist Helen Beulah Thompson Gaige,[7] who collected the first specimen in the Big Bend region of Texas in 1928.

[1] 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.

[citation needed] Adults of T. gaigeae have a straight carapace length of 5 to 11 inches (13 to 28 cm).
