Sonoran Black Kingsnake

Range:

Sonoran Desert

Habitat:

Desert

Characteristics:

Generic name means ‘shiny skin’. Scales are smooth. Color is black with a lighter belly.

Behavior:

Constrictor but often vibrates tail as ‘bluff’. Hides under logs or stones. If caught, can be vicious, biting and chewing hard, but after adjusting to captivity, usually becomes quite good-tempered. Because of their snake-eating habits, they are often caged separately in captivity. Sometimes rolls into a ball with its head at the center and everts lining of cloaca as ‘bluff’. Chiefly terrestrial but some species climb into trees after birds. Usually crepescular, but desert species often nocturnal.

Reproduction:

Mate from mid-March to early July. Oviparous, laying 6 – 12 eggs in a clutch; incubation period 66 – 83 days. The striped and banded phases often occur within offspring of same clutch of eggs.

Interesting Facts:

Valuable in controlling rodents and venemous snakes. Presence of king snake nearly assures absence of rattlers in area. In the presence of a king snake a rattler will neither strike nor rattle, but will lay with head low and raise center part of its body in a loop, with which it will strike heavy blows to the king snake.
