Python Morph

The Pythonidae, commonly known simply as pythons, from the Greek word python, are a family of nonvenomous snakes found in Africa, Asia and Australia. Among its members are some of the largest snakes in the world. Eight genera and 26 species are currently recognized.

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.
