The desert tortoise, Gopherus agassizii are mainly known for their long lives and survival techniques. Desert tortoises are classified in the class reptilia, and they are a member of the Testudinidae family. Desert tortoises are found in rocky terrains, deserts, canyons, and washes. Tortoises are very prominent for being slow, as they have a high domed shell, columnar legs with scales in the front. The desert tortoise, also known as Gopherus agassizii, can be found in the Mojave desert and the Sonoran desert of the southwestern United States. They are also found in the Sinaloan thornscrub of northwestern Mexico, southern Nevada, southeastern California, southwestern Utah and western Arizona.

On the basis of differences in characteristics, DNA, and geography, these were further classified in Agassiz's desert tortoise, also known as Gopherus agassizii, and Morafka's desert tortoise, also known as Gopherus morafkai. Both of these classifications of species occur on either side of the Colorado River. The Gopherus morafkai are found in the east of Colorado, and the Gopherus agassizii are seen on the west of the Colorado River, California. Desert tortoises may be referred to as a blend of two species and have now become very rare. So the next time you cross paths with desert tortoises, consider yourself lucky enough. To learn more about these adorable animals, we have gathered a set of interesting facts about them for you to read.

What is a desert tortoise's habitat?

Desert tortoises live in deserts that are really cold on winter nights and the extreme heat during summer days; therefore, in a nutshell, desert tortoises can sustain extreme temperatures. They dig burrows and hibernate in case of very high or low ground temperatures so as to maintain their body temperature. During winters, their metabolism rate slows as they don't get out of the burrows in search of food or to forage due to extreme cold. Desert tortoises have the ability to adjust and sustain in severe temperatures. Hence there are several variations in desert tortoise habitat, from rocky terrains to sandy flats and deserts.

Who do desert tortoises live with?

Desert tortoises are solitary, and so they love to live alone, but at times they share their burrows with some other mammals, reptiles, or birds. Sometimes they share burrows with other desert tortoises, too, but often there's a fight for dominance. Moreover, keeping two female and one male desert tortoises or more than two of the same sex is also suggested.

How long does a desert tortoise live?

The desert tortoise is known for its long life span, which ranges from 50-80 years. And a desert tortoise living in a zoo has a greater lifespan than that of a desert tortoise living in the wild as they do not have to face the predators or their no sort of threats. A desert tortoise living in the wild has to sustain the loss or destruction of habitat, which results in various reasons of their mortality like upper respiratory tract disease, and herpesvirus.

How do they reproduce?

Desert tortoises have a low rate of reproduction. They mate during the spring and autumn season and have an incubation period of about three to four months. Their mating season lasts from August to October. They generally lay eggs in the month of May and July and can lay up 2-14 eggs at a time. The number of eggs they lay is referred to as clutch size in desert tortoises. These hatchings often come out in Mid-August and October, and the mother doesn't need to protect her offsprings as they are born with basic sustainability skills, and they fend for themselves. A desert tortoise becomes mature at the age of 12-20 years.

What is their conservation status?

According to the US Fish and Wildlife Service, desert tortoises' conservation status was classed as Threatened in the early 1990s. In the last 20 years, the population of desert tortoises in the Mojave and Sonoran deserts of California and other places like Nevada and Arizona has reduced by 90%. The Mojave desert tortoise is classified as endangered species as it occupies the west and north of the Colorado River.

They have stumpy legs, which is apparently the main reason for being slow, and have flattened front limbs, which helps them dig burrows and sand to hibernate during extreme temperatures. Their domed shell helps them with thermoregulation as there is space for lungs, which ultimately helps them survive in such extreme temperatures. The male desert tortoises have a horn-like forward projection on their lower shell or plastron, and this projection is known as the gular shield.

The Mojave desert tortoise and the California desert tortoise have an abundance of such annual plants, which makes it suitable for them to survive. An adult tortoise can sustain for a year without water as they have huge urinary bladders which store up to 40% of their weight in water. And in dry seasons, they depend on the moisture from some plants and annual wildflowers.

Would they make a good pet?

They would make a good pet, but there are certain challenges in keeping them as a desert tortoise diet includes certain plants that may not be available, so providing the proper and sufficient nutrition is challenging. As a desert tortoise has a long life expectancy so keeping them needs commitment as leaving them back in the desert may be harmful to both the wild desert tortoises as well as themselves as the risk of upper respiratory disease increases. Therefore it is recommended to either visit a zoo and meet them or learn about them on the internet.
