Eyelash Pit Viper

Another creature captured in Costa Rica, this eyelash pit viper carries venom in its hinged, hollow fangs. Eyelash vipers have many color variations including brown, red, and yellow like this one, and are named for the scales above their eyes resembling eyelashes and the heat-sensitive pits between their eyes and nostrils that allow them to sense prey. Unlike most other species of snakes, eyelash vipers have rough, not smooth, scales that protect the snake while meandering through its arboreal habitat. These snakes are also ovoviviparous; fertilized eggs develop inside the mother and hatchlings are either born live or immediately after eggs are laid. Interestingly, a single clutch of eggs may contain vipers of every color variation. Eyelash pit vipers were, quite happily, removed from CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) threatened list in 2002.
