The variable pocket gopher (Heterogeomys heterodus) is a species of rodent in the family Geomyidae. [2] It is endemic to Costa Rica, usually being found in grasslands and tropical forests at higher altitudes, up to 8,000 feet. It is threatened by habitat loss, but are sometimes kept as pets in the United States and elsewhere.

The gopher typically has soft and dense fur colored blackish on the posterior and pale on the anterior. Its dentition features a longitudinal groove on outer face of each upper incisor. Large specimens range in length from 12 to 19 inches in length and weigh 16 to 35 ounces.

Some authors classify it in the genus Orthogeomys , but recent research has allowed this and its related species to be classified in the genus Heterogeomys . [3]

Heterogeomys is a genus of rodent in the family Geomyidae, found in Mexico, Central America and Colombia. Heterogeomys are a small genus of rodents commonly known as pocket gophers, though the term applies to all genera within the family Geomyidae. The name pocket gopher was earned for this family because of their fur lined cheek pouches that can be used for carrying food. These pouches can also be turned inside out. Species of Heterogeomys are regarded as pests, one of less than 5% of rodent species classified as pests, and the history of man's attempts to control their populations reaches back into Mayan times. Despite some efforts to the contrary, populations of Heterogeomys seem to be on a general upwards trend. Furthermore, all of the species of Heterogeomys are considered to be of Least Concern in the World Status Key.
