The tropical pocket gopher (Geomys tropicalis) is a species of rodent in the family Geomyidae. It is endemic to Mexico. Its natural habitat is hot deserts. It is threatened by habitat loss.

Description[edit]

The tropical pocket gopher is cinnamon to brown on its back and head. Its underparts have white fur, and its tail is mostly naked. They have large front feet, along with small eyes and a thick body.[2] Males are on average larger than females.[3]

Distribution and habitat[edit]

The distribution of the tropical pocket gopher is restricted to a small area near the Southeastern tip of Tamaulipas, Mexico.[4]

Genetics[edit]

The tropical pocket gopher has a diploid number of 38. This is low compared to similar species. This could help them adapt to their restricted habitat. Since their numbers are low there is a high risk of them losing too much genetic variability to survive.[5]
