Species Description

Like all subspecies of the willardi complex, this beautiful and relatively small rattlesnake gets their common name from the upturned scales that border the snout. This subspecies of ridge-nosed can be found in wooded, mountainous habitat of Sierra del Nido in Chihuahua, Mexico. There is not much known about this subspecies of willardi and more research needs to be done.

A large portion of this species diet in the wild consists of centipedes.
