Species Description
Also called the dusky Baja California rattlesnake, this medium-sized species is found on the San Quentin Plain in Baja California del Norte. The habitat in the San Quentin Plain is very rocky with brush, and it's more mesic than the surrounding deserts. The Rosario rattlesnake probably primarily consumes small mammals as an adult and utilizes burrows for shelter and to hunt. This species gives birth to less than ten neonates.
Extremely little is known about this species due to its very restricted but largely inaccessible habitat.
