Transcript of The Pit viper

Characteristics and Adaptations
These snakes range in size from the hump-nosed viper, that grows to an average only 30–45 cm , to the bushmaster, a species known to reach a maximum of 3.65 m (12.0 ft) in length—the longest venomous snake in the New World.

They all share a common characteristic: a deep pit, or or fossa in the loreal area. These loreal pits are the external openings to a pair of extremely sensitive infrared-detecting organs, which in effect help them find and perhaps even judge the size of the small, warm-blooded prey on which they feed.

Venomous snakes have fangs already loaded with venom and poison as soon as they are born.

Pit viper
The Pit viper
The Crotalinae are commonly known as pit vipers, crotaline snakes, or pit adders.

This group of snakes include rattlesnakes, lanceheads and Asian pit vipers. They are a subfamily of vipers (Viperidae) and the genus for this subfamily is Crotalus.

They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on either side of the head.
While pit vipers are particularly keen of areas where basking is
optimal, their habitats range from the rainforests to the deserts .
With such a variable habitat preference,while one member, the
cottonmouth, is known to be semi-aquatic .

This family of snakes is found in the Old World from eastern Europe eastward through Asia
to Japan, Taiwan, Indonesia, peninsular India, Nepal, and Sri Lanka. In the Americas, they range from southern Canada southward to Central America to southern South America.
Habitat and Geographical range
Pit vipers are viviparous, which means their babies are born live (no eggs). The eggs open inside the mother's body. The number of snakes born in a litter ranges from 6 to 50.

Vipers have a pair of hollow fangs. They lie up against the roof of the mouth and shoot out when the viper strikes. The venom of pit viper attacks red blood cells and their ability to carry oxygen.

One of the predators of the viper is the King Cobra. The pit viper preys on animals such as mice, lizards, and birds.


The pit viper hunting
The receptor cells of the pit viper are so sensitive that they can detect changes of 0.002°c which also help the pit viper to find food such as mammals , birds in dark places or during night.

Pit vipers are both nocturnal and diurnal.
