The chain kingsnake is widely distributed in North America, being found in over 30 states in the U.S. as well as Mexico.
They prefer open areas and their habitats include deserts, grasslands, marshes and swamps, and woodlands.
It is believed that chain kingsnakes are diurnal (meaning they hunt during the day), though they may also be crepuscular (hunting at dawn and dusk).
In addition to eggs, lizards, frogs and small mammals, chain kingsnakes are most noteworthy for eating other snakes, which is where the name “kingsnake” comes from. Its diet of snakes even includes venomous snakes such as coral snakes, rattlesnakes and copperheads. It is immune to the venom of these snakes.
