California Kingsnake
Lampropeltis californiae
On This Page▾
🌍 Overview
The California kingsnake is a non-venomous colubrid found throughout the western United States and northwestern Mexico. "King" snakes earned their name from their ability to kill and consume venomous rattlesnakes - they are immune to pit viper venom. Highly variable in pattern and coloration, they can mimic the banding of venomous coral snakes in some regions. Hardy and easy to care for, they are a popular beginner species.

📜 History
This was one of the first snakes bred regularly in captivity, which is why it entered the hobby with a deep catalogue of patterns and morphs while most species still had none. Ease of breeding is the reason: a hardy colubrid that takes rodents readily and tolerates a simple setup is a species a hobbyist can work with over generations. The result is that a beginner buying one today is buying the product of decades of selective breeding rather than a recently collected wild animal.
