The Arizona ridge-nosed rattlesnake (Crotalus willardi) was the last rattlesnake to be named by herpetologists (grown-ups who study snakes).

This snake is small, rarely weighing more than 3-4 ounces as an adult or growing longer than 24 inches.

The ridge-nosed rattlesnake lives only the Huachuca, Patagonia, and Santa Rita Mountains in the south central part of Arizona.
