Venomous Snakes Of Costa Rica Eyelash Viper
An eyelash viper (Bothriechis schlegelii) coils on a tree branch during a wildlife photography workshop near Boca Tapada in the San Carlos canton of Alajuela province, Costa Rica, on June 27, 2026. The arboreal pit viper is named for the modified scales above its eyes that resemble eyelashes and delivers venom that affects blood and tissue, causing pain, swelling, and bleeding. Adults typically measure 20 to 28 inches in length, with females growing larger than males. (Photo by Ronen Tivony/NurPhoto)
