Beaded Lizard

Zoo Location: Reptile Tropics
 Beaded Lizard

This species is found in Southern Texas in the USA, through Western Mexico to Northern Guatemala.

Wild Diet

Beaded lizards are carnivores and their diet consists of eggs, young birds, smaller snakes and lizards, insects, rodents and carrion.


They like to hide under rocks or in burrows, preferrably not of their own making, and near to permanent water sources. This species is one of two venomous lizards, but unlike a lot of reptiles the beaded lizard does not have poisonous fangs. Instead it has to let its saliva penetrate the victim after chewing on it.


Breeding season occurs in the springtime and males will fight each other for the opportunity to mate with a female. These battles can last for hours.
Two months after mating anything from 2-20 eggs are laid in a burrow about 12cm deep. Five months after being laid, the eggs will hatch and the young will emerge.


The species is classified as being of Least Concern but is losing habitat due to very rapid human development, and also face threats of the growing pet trade and fear of death from people.
