Desert Night Lizard

Desert Night Lizards make great pets since they are small and have fascinating behavior. They eat spiders, small insects, and termites. On average they are born 1 inch long and will grow to be just 4 inches, and live to be about 8-10 years old.

Desert Horned Lizard

Desert Horned Lizards love ants, but also eat lots of invertebrates. They can lay up to 31 eggs. Their eggs are cream colored, tough and have a leathery coat. They also do a lot of things to get away from predators including playing dead, running away, and then suddenly turning around to face the predator, shaking their tail in leaf litter.

Texas Horned Lizard

The Texas Horned Lizard grows to be about 5 inches if female and 4 inches if male. They live about 5 years in the wild and 7 years in captivity. Horned Lizards eat a diet of mostly ants, but also eat other small insects, fruits, and vegetables. They have several enemies including coyotes, hawks, snakes, and people.

Legless Lizard

We do not know how long a Legless Lizard lives in the wild, but in captivity it lives about 20 years. They are nocturnal in warmer areas, but in cold areas, they are active during day. They grow to be 40 inches when full grown, and do have legs that are 2 milliliters long, but aren’t useful in any way.

Six-Lined Racerunner

The Six-Lined Racerunner is the most common lizard in North America.It can eat a variety of insects and invertebrates like moths, spiders, and grasshoppers. They grow to be about 6 to 10 inches, and can run up to 18 mph. They are adapted to very dry and warm conditions.
