The Eyelash Viper is an arboreal venomous snake, found in Central and South America, with a diverse array of skin colors, with the yellow color potentially being the most impressive. It is called Eyelash due to the scales right on top of the eyes. They grow up to 82 centimeters in length, which is not very long between viper species. Its head is triangular in shape and its tail is prehensile, helping it grab branches to maintain its balance. They hunt by ambush, waiting in a spot for prey, particularly birds during the annual migration.
