Great Basin Rattlesnake
(Crotalus viridis lutosus)
Great Basin Rattlesnakes can grow up to 5 ft. They seek refuge in mammal burrows, rocks, or caves. Most of them have a light stripe that runs from behind the eye to the corner of the mouth and dark dorsal blotches. They eat mammals, birds, eggs, lizards, and other snakes. This snake is poisonous and our most dangerous reptile.
