Chuckwalla: 21 Facts You Won't Believe!

Chuckwallas are large lizards found in the North American desert

The chuckwallas, scientific name Sauromalus, are a part of the lizard family and are found largely in the North American desert. These are reptiles and fairly large in size. These reptiles are found in thousands and are mostly herbivorous in their eating habits.  The common chuckwalla species' conservation status is Least Concern. Different types of subspecies are found in different locations. For example, Santa Catalina chuckwalla is found in the peninsula of Baja California.

Common chuckwalla, Sauromalus ater, are rock dwellers. These are found in burrows or crevices in the desert areas of the Sonoran or Mojave desert. These burrows are generally naturally formed spaces not made by the chuckwallas as such. The common chuckwalla is part of the iguana family and has all the characteristics of the lizards of the desert. Chuckwallas are quite happy leading solitary lives in their burrows or crevices in the desert sand. They spend a lot of time basking in the desert sun. They also keep looking for their favorite foods and scurry into their burrows in the face of any danger.

The tail is wide at the base and the top is blunt. The tail has thick scales. The upper side of the body is black in color for males. This includes the shoulders, head, and upper body portions. The color of the lower portion of the males is dependent on the habitat. The lower body of males could be red, yellow, orange, or grey. They have nasal salt secreting glands with specialized cells and gut flora to help them break down cellulose from plants.

Females are yellowish-gray in color. So are the young males. Young chuckwallas have tails that have wide bands.

How cute are they?

One cannot really categorize the chuckwallas as being cute in the traditional sense of the word. They are part of reptilia that crawl with the lower part of the body touching the desert sands. Lizards are generally not considered cute.

The chuckwallas are able to communicate through the bobbing of their heads. They do not make any particular sound as such. They also do mouth gaping.

Chuckwallas eat fruits, vegetables, flowers, and some insects as well. They derive their water from their regular diet of these plants, fruits, and vegetables. This is because chuckwallas are desert dwellers where water supply is scarce.

Would they make a good pet?

It is possible to keep the chuckwalla species at home as pets. This is because these lizards are not poisonous and quite harmless. In fact, a pet chuckwalla can be quite docile by temperament. You have to make sure you have a proper enclosed space for the chuckwalla species to live in. This enclosure needs to be cleaned from time to time. It is recommended that the area be cleaned every four weeks. This will ensure that the area is hygienic for the chuckwalla species to thrive in. As the chuckwalla can be rather stout and bulky, the enclosure should be at least 4 feet long.

Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.

Usually, an ideal chuckwalla iguana cage would be 4 x 2 ft in dimension. This would be apt to allow the chuckwalla enough space to back in the sun and also move about at ease. The vents in the cage should be large. This helps in providing ample air for the chuckwalla to breathe. It also helps if the cage of the chuckwalla pet loses heat from one side. The specific area where the chuckwalla lizard resides inside the cage should have a non-variant temperature.

Beech chip wood makes for a good covering to the base of the cage. It is easy to clean and maintain as a habitat in captivity.

Being desert lizards, chuckwallas are used to basking in the sun in the wild. When caged it makes sense to provide a lamp on one side of the enclosure to ensure proper chuckwalla care. The lamp should also have a thermostat to ensure that the temperature is constant. Without this, the cage could become too hot for the pet chuckwalla’s comfort.

Did you know...

that the male chuckwallas fight with other males for mating with females. This is one of the most popular chuckwalla lizard facts. They also fight with each other for territorial rights. The fighting wins are often based on the relative sizes and weights of the warring males.

Also, in some tribes among the native Americans, chuckwallas were reared for their meat as food.

Chuckwallas can be fed the same things that they feed on in the wild. You can feed them with leaves as well as vegetables and fruits. They eat strawberries, buds, creosote leaves, and also ragweed and browneyes. These reptiles are not very choosy about their eating habits.

How does a chuckwalla protect itself from predators?

When chuckwalla faces danger, they use the tight crevices found between the rocks to protect themselves. Because of the flaps of loose skin, their body is inflated which fills the entire space. This makes it difficult for the predator to pull them out.

How do chuckwallas cope with excess salt in their diet?

Chuckwallas cope with the excess salt present in their diet in an interesting way. They sneeze the salt out of their body to get rid of it. This is why there is salty residue found around their nostrils.
