Desert Tortoise (Gopherus agassizii)

General Description: A turtle in the Mojave Desert with a moderately domed, brownish shell. This is the only "land turtle" in the desert around Las Vegas.

Taxonomy: Tortoise Family (Testudinidae).

Technical Description: A terrestrial "turtle." Carapace moderately domed, brownish; can exceed 14-inches long. Hind legs stumpy, round, and elephant-like. Front legs broadly flattened with leathery skin and large scales. Male with indented plastron; female with flat plastron.

Diet: Primarily eats annual forbs and grasses that germinate during springtime after good winter rains. Also eat cactus and other low-growing plants. Drink standing water when available, through their nose. When food is unavailable, can stay in underground burrow for more than 6 months.

Habitat: Most common in Mojave Desert Scrub habitat type, especially desert scrub and wash habitats dominated by creosote bush. Found in valleys and on bajadas and hills below 4,500 ft elevation. Less common in the lower-elevation Creosote-Bursage Flat habitat type. An important habitat requirement is the presence of annual wildflowers and native grasses that are eaten during spring.

Range: Southeastern California, southern Nevada, and southwestern Utah. In western Arizona and western Mexico, they have a different species of tortoise: Sonoran Desert Tortoise (Gopherus morafkai), which formerly was considered the same species as Mojave Desert Tortoise.

Breeding: Mate in the spring, lay 1-15 eggs per clutch during spring through mid-summer, hatchlings emerge in the fall shortly before going into hibernation.

Similar Species: This is the only species of tortoise in Nevada. The Sonoran Desert Tortoise occurs across the Colorado River in Arizona.

this might be the last face you ever see!

Comments: Tortoises dig dome-shaped burrows, usually in the sides of washes or at the base of shrubs. If you look into burrows to try to find them, expect to also see creatures such as rattlesnakes that use the burrows. Tortoises can live longer than 50 years.

Special Remarks: Tortoises west and north of the Colorado River are listed and protected as Federally Threatened under the Endangered Species Act; individuals may not be taken from the wild. Pet tortoises can be obtained from the Desert Tortoise Program.

Desert Tortoise (Gopherus agassizii) Desert Tortoise males have chin glands that become enlarged (like this) during the breeding season. This is a good way to determine gender in tortoises without picking them up to feel the plastron.

Typical tortoise burrow: notice the dome-shaped roof (inward sloping walls), flat floor, and straight tunnel. Compare this shape with the shape of Kit Fox burrows, which have vertical sides and a tunnel that usually curves to the side.

We can tell this big buck is a male from the chin glands without pulling him out of his burrow.
