Western Pygmy Rattlesnake
This is one of the smallest species of rattlesnakes in North America. General color is light grayish-brown, with a row of small, dark brown spots on the back and similar spots on each side. Most specimens also have a rust-colored stripe down the back. The belly is usually gray. The pygmy rattlesnake has a thin tail and a tiny rattle. The sound of the vibrating rattle is a faint buzz like the sound of a grasshopper.
