Bothriechis schlegelii

Bothriechis schlegelii, known commonly as the highland eyelash-pitviper, Schlegel's eyelash-pitviper, or eyelash viper, is a species of pit viper in the family Viperidae, native to Colombia.

Somewhat small, arboreal snakes, B. schlegelii is perhaps best known for the namesake superciliary ("eyelash") scales above its eyes, and for having distinctly keeled or "raised" scales covering the bulk of its body. The species is also known for producing a veritable rainbow of color forms (morphs). It is the most common of the green palm-pitvipers (genus Bothriechis), and is often present in zoological exhibits, owing to its general hardiness. The specific name schlegelii honors Hermann Schlegel, who was a German ornithologist and herpetologist.
