The Mexican pygmy rattlesnake is a small, venomous pit viper. It lives in the mountains of central and southern Mexico, and nowhere else in the world. Its venom and its rattle make it a useful animal to learn to recognise.1

2

A genetic study using nuclear markers places it at the base of its species complex, meaning it is the earliest branch among its close relatives.1
