The Gila Monster Heloderma
suspectum occurs from extreme southwest Utah to southern Sonora and northern Sinaloa;
extreme southwest New Mexico to southern Nevada and just into California.
The northern subspecies is the
Banded Gila Monster H. s. cinctum and the southern subspecies is the Reticulated
Gila Monster H. s. suspectum. See Map
Heloderma suspectum
occurs up to an elevation of 1500 meters. It has been observed to be more common in the
wetter, rockier paloverde-sequaro desert scrub association than the drier, sandier
creosote bush-bersage association. Heloderma suspectum also seem to prefer rocky
foothills and avoid open flats and agricultural areas. |
