Coast Night Snake vs. Western Rattlesnake

Night snakes are often mistaken for young rattlesnakes: both are blotched, with cat-eye pupils. Their records overlap widely. A: Flat and narrow, no pit in the Coast Night Snake; broad and triangular, much wider than the thin neck; a pit between the eye and nostril in the Western Rattlesnake. B: Thin and pointed, no rattle in the Coast Night Snake; a rattle, or a single button on the young in the Western Rattlesnake. The night snake is harmless to people; the rattlesnake is venomous: leave it alone.
