Crotaline (Crotalus spp.)

Crotaline refers to a group of venomous snakes known as pit vipers, which include species from the Crotalus genus, like rattlesnakes. These snakes are characterized by their distinctive triangular heads, slit-like pupils, and heat-sensing pits located between their eyes and nostrils. This unique feature allows them to detect warm-blooded prey, such as rodents. Rattlesnakes are also known for their rattles at the end of their tails, which make a buzzing sound as a warning when threatened. Pit vipers play vital roles in their ecosystems as predators and are found primarily in the Americas.
