The Californian Kingsnake is native to western USA and northwestern Mexico. It used to be considered a subspecies of the
Common or Eastern Kingsnake (L. getula). Kingsnakes are so called because they eat other snakes (and lizards, rodents, etc.).
They are diurnal and non-venomous, squeezing prey to death. They have become popular in the pet trade and are bred in different colour
"morphs", such as the aberrant colours/patterns above.
They can grow to some 4 feet (1.2 metres) length. Albino (above) and leucistic forms also exist, especially in captivity.
