Crotalus willardi amabilis, the Del Nido ridge-nosed rattlesnake, is a subspecies of ridge-nosed rattlesnake native to Sierra del Nido, Chihuahua, Mexico. As with all rattlesnakes, it is venomous. [1]
Crotalus willardi amabilis is recognised by its facial stripes, its red/pink colouration and its specific scale counts. The subspecies is distinguished from its sister subspecies by a higher number of dorsal blotches which averages 39.5. [2]
Sexual dimorphism can be seen in its specific scale counts and tail length, with males' tails averaging 11.5% of their length, and females' tails averaging 9.3%. [2]
The subspecies is known to inhabit isolated, high, forested areas of Sierra del Nido. [2]
Crotalus willardi amabilis is known to be ovoviviparous. [1]
