Bothriechis schlegelii
The eyelash viper (''Bothriechis schlegelii'') is a venomous pit viper species found in Central and South America. Small and arboreal, these snakes are characterized by their wide array of color variations, as well as the superciliary scales over the eyes. They are the most common of the green palm-pitvipers (genus ''Bothriechis''),〔 and are often present in zoological exhibits. The specific name ''schlegelii'' honors the German ornithologist, Hermann Schlegel. For other common names see below. No subspecies are currently recognized.
==Description==
The eyelash viper is a relatively small species of pitviper, with adults ranging from long, and females being longer and more variable in size than males, which can grow to long.〔 They have a wide, triangular-shaped head, and eyes with vertical pupils. Like all pit vipers, they are solenoglyphous, having large, hypodermic needle-like fangs in the upper jaw that fold back when not in use, and have heat sensitive organs, or pits, located on either side of the head between the eye and nostril.
Its most distinguishing feature, and origin of its common name, is the set of modified scales over the eyes that look much like eyelashes. The eyelashes are thought to aid in camouflage, breaking up the snake's outline among the foliage where it hides. ''B. schlegelii'' occurs in a wide range of colors, including red, yellow, brown, green, even pink, as well as various combinations thereof. They often have black or brown speckling on the base color. No external features distinguish the two sexes.〔
