Ninia sebae, commonly known as the redback coffee snake[2] or the red coffee snake,[3] is a species of small terrestrial snake in the family Colubridae. The species is endemic to Mexico and Central America south to Costa Rica.[1] Although it resembles some venomous coral snakes in color and size, it is not venomous and seldom bites humans.[4][5]
The specific name, sebae, is in honor of Dutch naturalist Albertus Seba.[6]
Four subspecies are recognized as being valid, including the nominotypical subspecies.[2]
Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Ninia.
The preferred natural habitats of N. sebae are forest and savanna, at altitudes from sea level to 2,200 m (7,200 ft).[1]
Coffee snakes (species in the genus Ninia) are thought to rely on concealment, flight and intimidation to avoid predation.[3] These snakes were observed either flattening their entire bodies when alarmed,[7] or remaining motionless in whatever position they were discovered.[8] In a more recent study these snakes, when touched, displayed a flattened head and neck, and raised their anterior third or half.[3]
N. sebae preys upon earthworms.[2]
