At a length of up to two feet (0.6 meters) and a maximum weight
exceeding five pounds (2.3 kilograms), the venomous Gila monster
(pronounced HEE-luh) is the largest lizard native to the United States.
GILA MONSTER
Easily
identified by their black bodies marked with dramatic patterns of pink,
orange, or yellow, Gilas are found in the Mojave, Sonoran, and
Chihuahuan deserts of the southwestern U.S. and northwestern Mexico.
They take their name from Arizona's Gila River basin, where they were
first discovered.
The Gila monster is one of only a handful of
venomous lizards in the world. Others include the similar-looking
Mexican beaded lizards.

The Gila monster is one of only two species of venomous lizards; both are of the family
Helodermatidae and both are similar in appearance and habits. Its venomous cousin, the
Mexican beaded lizard (
Heloderma horridum), is slightly larger and darker.
Most of the Gila monster's teeth have two grooves that conduct its
venom, a nerve toxin, from glands in the lower jaw. The toxin is not
injected like that of the snake, but flows into the wound as the lizard
chews on its victim. While the bite can overpower predators and prey, it
is rarely fatal to humans.
There are two subspecies of Gila monsters in the deserts of the Southwest:
- H.s. suspectum (reticulate) resides primarily in the Sonoran and Chihuahuan deserts. Adults are mottled and blotched.
- H.s. cinctum (banded) resides primarily in the Mojave Desert. Adults have a broad double crossband.
Range
Mojave, Sonoran and Chihuahuan deserts of extreme southwestern Utah,
southern Nevada, southeastern California, Arizona and southwestern New
Mexico into Mexico.
Habitat
Desert and semiarid regions of gravelly and sandy soils with shrubs.
Found under rocks, in burrows of other animals and in holes it digs
itself.
Behavior
During warm weather the Gila monster
feeds at night
on small mammals, birds and eggs. Fat stored in the tail and abdomen
during this period is utilized during the winter months. Both species of
Heloderma are sluggish in habit, but they have a strong, tenacious bite.
