Adaptations The colorful, beadlike skin of the gila monster helps with camouflage. Its claws are used for digging burrows and for digging out other animals' eggs. Its tongue helps it to hunt and to receive information about its surroundings by picking up the scents in the air. They also can store fat in their tails. This is very important to the survival of the Gila monster during times in which food supply is diminished, during hibernation and during pregnancy. |

Wild Status Gila monsters are quoted as being "Species not presently threatened, but may become so unless trade is regulated." The Gila Monster is not endangered.

Diet In the wild Gila monsters eat small mammals, lizards, frogs, insects, carrion, birds and birds' eggs. They hunt primarily with their sense of taste and smell. As they grab their prey with their jaws venom flows into the bite wounds. Their venom attacks the nervous system of their prey. |
Predators Humans are the main predator of this species. Some people consider them to be prized possessions because they are not often seen in the wild. They have few other natural predators. |
