Desert Kingsnake vs Speckled Kingsnake
A desert kingsnake and a speckled kingsnake are close relatives that share a natural resistance to pit viper venom and a willingness to prey on other snakes, but each has settled into a different part of the south-central and southwestern United States.

Desert Kingsnake vs Speckled Kingsnake: common questions
How can you tell a desert kingsnake from a speckled kingsnake?
The desert kingsnake typically shows bolder yellow spots against a dark brown or black body and is found in genuinely arid desert habitat across the Southwest, while the speckled kingsnake shows a much finer, more evenly distributed yellow speckling across nearly every scale, earning it the nickname salt-and-pepper snake, and favours grassland and wetland-edge habitat farther east.
Do both the desert kingsnake and speckled kingsnake eat rattlesnakes?
Yes, both species share the natural resistance to pit viper venom typical of kingsnakes generally, allowing each to prey on venomous snakes such as rattlesnakes and copperheads within its own range with relatively little risk of serious harm from a defensive bite.
Why does one kingsnake live in the desert and the other in grassland?
The desert kingsnake has adapted specifically to tolerate the extreme heat and aridity of the American Southwest, while the speckled kingsnake instead favours the comparatively wetter grassland, farmland, and wetland-edge habitat of the south-central United States, a geographic and habitat split that keeps the two close relatives largely separated despite their similar biology.
