The western yellow-bellied racer (Coluber constrictor mormon),[1] also known as the western yellowbelly racer,[2] or western racer,[1] is a snake species endemic to Western United States, including California, Nevada, New Mexico, Utah, and Colorado.[3][4] It is a subspecies of the racer. It is nonvenomous,[5] and is recognized by its long and very slender shape.[6][7] It is visually similar to the eastern yellowbelly racer, which is also green, blue or brown with a yellow recognizable underbelly. Also named for its color, the Western Yellowbelly Racer is also gray with red or brown blotches when young.[8][9]
