Masticophis is a genus of snakes, commonly referred to as whip snakes or coachwhips, in the subfamily Colubrinae of the family Colubridae. The genus is endemic to the Americas.[1] Member species are characterized by having a long, thin body and are not dangerous to humans.
Distribution and habitat
[edit]Species of Masticophis are found in the United States, Mexico, Central America, and northern South America.[1]
Description
[edit]Adults of species in the genus Masticophis may attain a total length (tail included) from 1.52 m (5.0 ft) for M. lateralis to 2.59 m (8.5 ft) for M. flagellum. A distinctive character of this genus is the shape of the frontal scale (the large scale in the center of the upper surface of the head) which is bell-shaped and elongated. At the rear of the body, the dorsal scales are arranged in only 13 rows.[2]
