Rio Grande cooter

The Rio Grande cooter is found in the Rio Grande drainage of Mexico (Chihuahua, Coahuila, Nuevo León, Tamaulipas), New Mexico, and Texas.[2][3]

The preferred natural habitat of P. gorzugi is freshwater wetlands, at altitudes of 259–1,082 m (850–3,550 ft).[1][4]

The specific name, gorzugi, is in honor of George R. Zug, the Curator of Amphibians and Reptiles at the National Museum of Natural History.[5][6]
