Species Description

This large rattlesnake can reach up to 50 inches in length and resides in many of the western states along the Great Basin in dry and barren habitats. It is distinctly blotched typically with a banded tail before the rattle. This species used to be a subspecies under "oreganus" but has recently been elevated to its own species.

Fun fact: The Great Basin rattlesnake is extremely variable in coloration of its blotches and the rest of its body. The blotches may be dark like this, chocolatey, tan, silver, or different shades in between, and the background is just as variable. Most often, the blotches are either darker or a similar color to the rest of the snake.
