Geomys attwateri

Attwater's Pocket Gopher

Order: Rodentia
Family: Geomyidae


Conservation Status: Least Concern.

Common and abundant within its limited range in Texas, Attwater's Pocket Gopher requires habitats with vegetation dominated by grasses, which it feeds on both aboveground and belowground. Built to burrow, Attwater's Pocket Gopher is cylindrically shaped but stouter in the front. It is armed with long, strong claws, has tiny ears and eyes, and its incisors protrude beyond the lips. Its burrow systems are remarkably complex, as they have multiple loops and convolutions, rather than the simple lines and branches constructed by most pocket gophers. The average life span of this species is only 12.5 months.

Sexual Dimorphism:
Males are larger than females.

Average: 216.5 mm
Range: 192-235 mm

Average: 163 g males; 131 g females
