Clelia scytalina, commonly known as the Mexican snake eater[3] or zopilota de altura (highland mussarana),[4] is a species of snake in the familyColubridae. The species is endemic to the New World.
The head of C. scytalina is somewhat distinct from the neck. The eye is moderate in size, with a vertically elliptical pupil. The body is cylindrical, and the tail is moderately long.[4]
The coloration of juveniles is completely different from that of adults. Juveniles have a black head, a yellow or white nuchal crossband (collar), and a red body. Juveniles are often mistaken for coral snakes and killed.[4] Adults are uniform bluish black dorsally, and cream-colored ventrally.[5]
