Milk Snake Morph

The milk snake or milksnake, Lampropeltis triangulum, (French: Couleuvre tachetée; Spanish: Culebra-real coralillo; Lithuanian: Pienine gyvate) is a species of king snake.

Clever genetic manipulation is responsible for a wide variety of colors and patterns in modern snake breeding. In zoology these differences are known as morphs and are genetic mutations causing departures from the normal or "wild" type and appearance. One generally doesn't find large physical differences in morphs but color and pattern variations can be quite vast and amazing.
