Gophers have small eyes and a short, hairy tail, which they use to feel around tunnels when they walk backwards. Pocket gophers have often been found to carry external parasites including, most commonly, lice, but also ticks, fleas, and mites. [8] Common predators of the gopher include weasels, snakes, and hawks. [10]
The camas pocket gopher is a smooth-toothed pocket gopher of the genus Thomomys, within the pocket-gopher family Geomyidae. [4] The incisors of gophers in the genus Thomomys have characteristically smooth anterior surfaces, while those of Geomys have two deep grooves per tooth and those of Cratogeomys have a single groove.

The body gradually tapers from the head to the tail, widening a little at the thighs. Short hair covers the body and ranges in color from pale brown to black and is usually paler towards the belly area. The tail is short, thick, and bare with very little hair found at the base and averaging 65 mm (2.6 in) in length. The front feet are used for ...
The size, weight, and hindfoot length of the Idaho pocket gopher are variable, although typically no more than 150 millimetres (5.9 in), 90 grams (3.2 oz), and 26 millimetres (1.0 in) for each, respectively. The color of the back ranges from yellowish brown with dark brown tipped hair to grayish brown or fully dark brown, fairly uniform overall.
Like other pocket gophers, they have a large head, a short, muscular neck, small eyes and ears, and short legs. The forefeet are large with powerful digging claws, while the hindfeet are stout, with flat soles. There is a fur-lined cheek pouch on either side of the mouth, from which the name "pocket gopher" derives. Females have eight teats. [3]
Whitish hairs cover the tops of the feet, while the short, tapered tail is nearly naked. Fossorial adaptations include small eyes, short, naked ears, and large fore feet with heavy claws. Zygomatic arches are widely flared, providing ample room for muscle attachment, [ 5 ] although, unlike other pocket gophers, this species does not use the ...

Females are slightly smaller and both sexes weigh about 400 grams (14 oz). The dorsal surface is a dull greyish-brown and the ventral surface is whitish with darker patches.
Thirteen-lined ground squirrels can survive in hibernation for over six months without food or water and special physiological adaptations allow them to do so. [6] They alternate between torpor bouts of 7 to 10 days when their body temperatures drops to 5-7°C, and interbout arousals of less than 24 hours with their body temperature back to 37 ...
