Coniophanes is a
genus of
colubridsnakes,
commonly referred to as black-striped snakes, but they also have many other common names. The genus consists of 17
species, and despite the common name, not all of them display striping.
Snakes of the genus Coniophanes grow to a total length (including tail) of 31–46 cm (12–18 in) and are typically brown in color, with black striping down the sides and center of the back, and a red or orange underside. Some of the species, such as C. alvarezi, are solid brown.
Habitat and behavior
Coniophanes snakes are secretive burrowers. They spend most of their time digging into loose soils, forest leaf litter, or under rotting
cactus. They are
nocturnal, emerging from their underground retreats in the late evening to feed on
frogs,
lizards, small
rodents, and smaller
snakes.
Reproduction
Species in the genus Coniophanes are
oviparous, laying clutches of up to 10
eggs in loose soil. The eggs hatch in around 40 days, depending on relative temperature and humidity. Hatchlings are about 17 cm (6.5 in) in length.
