One of the most popular snakes in captivity, the California kingsnake can vary widely in appearance due to numerous naturally occurring and captive-developed color morphs
All kingsnakes are non-venomous, but are powerful constrictors and generally kill their prey through suffocation.
They are considered harmless to humans, but if handled it is common for this species to bite as well as excrete musk and fecal contents from their cloaca, but this latter habit is usually restricted to the females.In the winter, they will usually go deep underground and enter a hibernation-like state called brumation, which is characterized by a slowed metabolism and reduced activity.
And there was me thinking it was just Black Adder.........
