The Eyelash Palm-Pitviper is an arboreal venomous snake, found in Central and South America, with a diverse array of skin colors, the yellow color potentially being the most impressive and rendering them unmistakable, which gives them one of its most recognizable nicknames: “Oropel”, whose root is “oro” that means gold. It shares its genus with the Side-striped Palm-Pitviper.
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.
