Much of Grand Canyon is desert and riparian country, which means reptiles live here. Yes, those creepy, sneaky, crawly animals that many visitors might prefer to not see during their vacation and explorations.

There are approximately 47 species of reptiles in the national park. 10 are common along the Colorado River corridor and include lizards and snakes.

Below is a very brief sampling of some of the reptiles visitors may see while on their Grand Canyon vacation.

Desert Tortoise

The Desert tortoise is native to the Mojave and Sonoran deserts of the southwestern U. S. This tortoise may reach 10 to 14 inches in length. Male tortoises have a longer gular horn than females. Their shells have a high "dome" and are greenish-tan to dark brown in color. The animal's front limbs have heavy, claw-like scales and are flattened for digging. Back legs are shorter and more "stumpy."

Six rattlesnake species have been recorded in the park. Two are species rarely encountered, the South-western speckled rattlesnake and the Northern black-tailed rattlesnake. The other four rattlesnakes are subspecies of the Western Diamondback rattlesnake complex: the Grand Canyon pink rattlesnake, Great Basin rattlesnake, Mojave "green" rattlesnake, and Hopi rattlesnake. Of these, the Grand Canyon pink rattlesnake is the most common.
