The Lizard is a reptile with over 6,000 different species that is closely related to snakes; some lizards are even more closely related to snakes than to other lizards. Most lizards have four legs, eyelids that they can blink, smooth scales, exposed ear holes, and tongues that can smell. Lizards are primarily carnivorous animals, although some are vegetarian, that sit and wait for their prey, as opposed to actively hunting. Lizards are found on every continent, except for Antarctica. For defense and offense, lizards may be venomous, capable of camouflage, and able to lose and regrow their tails. Lizard’s scales do not grow with them, and the creatures will molt and shed their scales in order to grow.

What do lizards eat?

What lizards eat depends on their habitat and species. Many lizards are carnivores. Lizards typically eat insects like flies and crickets, snails, spiders, and caterpillars. The larger the lizard the larger the prey tend to be. Some lizards may also eat cicadas, small mammals, and other lizards.

Why do lizards do push ups?


Lizards do push ups to attract other lizards and display their strength as well as warn others to no intrude their territory. Lizards tend to do this ritual both at dawn and dusk. Their displays of strength help avoid physical confrontations between male lizards.

How long do lizards live?

The lifespan of a lizard depends on the species, size, and if it is in captivity or in the wild. Many lizards have an average lifespan of 15 to 20 years. Lizards in captivity can live between 4 to 6 years. Smaller lizards in the wild tend to live shorter lifespans since it is harder for them defend themselves against other predators.

Armadillo Lizard (Ouroborus cataphractus)
Comparison drawing of the Armadillo Lizard compared to other lizards

Also called the armadillo girdled lizard, the armadillo lizard (Ouroborus cataphractus) is a kind of lizard commonly found in the western parts of South Africa. Best known for its defensive adaptation, the armadillo lizard rolls into a ball by taking its tail in its mouth. This position, which gives this lizard its name, protects its underbelly when threatened while exposing the hard scales and spines along its head, body, and tail. It will hold this posture until the danger passes. Characterized as diurnal and territorial, the armadillo lizard inhabits the crevices of rocks in groups where the males are noted to protect these territories.

The Armadillo Lizard has an overall length between 3”-3.5” (7.5-9 cm), body width of .6”-.8” (1.5-2 cm), body height of .39”-.55” (1-1.4 cm), and weight between 1.8-3.5 oz (50-100 g). The typical lifespan of the Armadillo Lizard is between 10-25 years.
