The Texas tortoise (Gopherus berlandieri), is a species of tortoise in the family Testudinidae. The species G. berlandieri is one of six species of tortoises that are native to North America.
Geographic range[]
G. berlandieri is found from southern Texas southward into the Mexican states of Coahuila, Nuevo León, and Tamaulipas.
Etymology[]
The specific epithet, berlandieri, is in honor of naturalist Jean Louis Berlandier, who worked for the Mexican government on one of the first biological surveys of Texas.[1][2] As such, some sources refer to it as Berlandier's tortoise.[2][3]
Biology[]
The Texas tortoise, unlike other species of gopher tortoise, is not an adept burrower. Its preferred habitat is dry scrub and grasslands. Succulent plants, a preferred food of the Texas tortoise, are common in these areas. It especially likes the fruit of cacti such as the prickly pear.
Conservation status[]
Though considered an animal of low concern by the IUCN Red List, the Texas tortoise is listed as a threatened species in the state of Texas, and thus protected by state law. It is illegal to collect or possess them. The Mexican federal government list Gopherus berlandieri as A (= Threatened) in Mexico.[4] Likewise, using Environmental Vulnerability Scores, Gopherus berlandieri scored 18, a high vulnerability species on a scale of 0-20, in evaluations of both Tamaulipas and Nuevo Leon herpetofauna.[5][6] In 2018, the IUCN Tortoise and Freshwater Turtle Specialist Group recommended a re-assessment and re-classification of all six Gopherus species[7] This reclassification would move G. berlandieri from Near Endangered (NE) to Near Threatened (NT).[7]
