They are non-venomous and are commonly found in the US (southern California, Arizona and Nevada) and Mexico (Baja California and Sonora). Although the Black Mamba is known as the world’s fastest snake, reaching top speeds of 10-12 mph in short bursts over level ground, the Red Racer is the fastest snake in the desert and can move at up to 7 mph with its whiplike body.
Needless to say, they are at their most comfortable when surrounded by the open and rocky setting of the desert. All snakes tend to be aggressive and the Red Coachwhip is no exception. They live on a diet of small animals such as mice, lizards, other snakes, birds and their eggs, bats and amphibians etc. And kill their prey by crushing them in its jaw - they are not constrictors and do not squeeze their prey to death.
Red Racers are hot-tempered and although they are not poisonous, they are still dangerous and can tear flesh with a single bite. Handling them should be avoided at all times.
