Botta's pocket gopher skull and teeth from Elliot 1901. Botta's pocket gopher is a medium-sized gopher, with adults reaching a length of 18 to 27 cm (7.1 to 10.6 in), including a tail of 5 to 6 cm (2.0 to 2.4 in).
Pocket gophers are solitary outside of the breeding season, aggressively maintaining territories that vary in size depending on the resources available. Males and females may share some burrows and nesting chambers if their territories border each other, but in general, each pocket gopher inhabits its own individual tunnel system.
Pocket gophers have special visual adaptations to match their extreme and unique subterranean lifestyle. Though the size of their eyes are typical for rodents, the lens is able to transmit light rays that fall into the ultraviolet range.
A long-term controlled study of tunnel excavation by plains pocket gophers found that the rate of tunnel construction ranges from a high of 2,059 cm/week of new tunnels to a low of none over several weeks during the summer. About 30 to 50 m (98 to 164 ft) of tunnels were open at any one time.
Tunnel systems constructed by the camas pocket gopher can be complex, with some tunnels exceeding 240 m (260 yd) in length. About 90 mm (3.5 in) in diameter, the tunnels are up to 0.91 m (3.0 ft) deep. [ 10 ]
Northern pocket gophers rarely appear above ground; when they do, they rarely venture more than 2.5 feet (0.76 m) from a burrow entrance. Underground, however, they often have tunnels that extend hundreds of feet where they live, store food, and give birth to their young. [2]
Mazama pocket gophers are light brown to black in color, with adults ranging in size from 5 to 6 inches (13 to 15 cm) in length. The Mazama pocket gopher’s distinctive features include pointed claws, long whiskers, and protruding chisel-like front teeth. [6] The pocket gopher serves as prey for a variety of predatory species.
The pocket gophers are considered to be medium to small in size in the order Rodentia. Baird's pocket gopher has a cylinder shaped body with most of its weight carried near its head. The zygomatic arch is shorter than the width of the mouth, meaning the dorsal of the animal exceeds the jugal bone. The neck is a little thinner but the heaviest ...
