Zoopedia Description
General[]
Population In Wild: Unknown
The desert horned viper (or Cerastes cerastes) is a venomous snake native to the deserts and semi-deserts of Northern Africa and the Middle East. It is also known as the Saharan horned viper. The body of the desert horned viper is colored, often with a paler underside. They may have slightly darker brown mottling on their scales as camouflage. The head is large and triangular. Most notably, they may have distinctive, pointed horns above their eyes, from which they get their name. Males and females look alike, although females tend to be slightly larger. Their body length varies from 11.8in to 23.6in long.
Desert horned vipers are a species of Least Concern and are not endangered. Their population in widespread and remains stable.
Social[]
Desert horned vipers are solitary. They only interact with other individuals to mate.
Reproduction[]
Breeding in desert horned vipers takes place while buried in sand, so very little is known about it. Mating events appear to take place in April, when a male and female viper meet. It is assumed they locate each other through pheromones. Copulation may last 3 to 4 days, after which the snakes part ways again.
Soon after mating, the female viper lays a clutch of 8 to 23 eggs underneath rocks or in an abandoned burrow. She does not stay with the eggs and no parental care is provided. The eggs hatch after an incubation period of 50 to 80 days.
Hatchlings are independent from birth and reach sexual maturity at around 2 years old.
