The viperidae (vipers) is a family of venomous snakes. they are also known as viperids. Vipers are members of the squamata order of reptiles, which includes snakes and lizards. The name “viper” is derived from the Latin word vipera, -ae, also meaning viper, possibly from vivus and parere, referring to the trait viviparity common in vipers but not in snakes at large. The term viperid also is used for members of viperidae and offers greater specificity than the term viper in distinguishing this family from its subfamily Viperinae, whose members technically may be known as viperines. they will survive farther north and south of the equator than most snake species.
Distribution and habitat
In the old world, viperids are set everyplace. Viperid snakes are found within the Americas, Africa, and eurasia. within the Americas, they’re native from south of the 48th parallel, through the united states, Mexico, Central America, and into South America. Viperids are found in wide variety of habitats, including terrestrial and arboreal, and grasslands, dry steppe, mountains, forests, savannas, and then forth.
Vipers have a triangular-shaped head. Most vipers are slender to stout-bodied snakes with a short tail. Some vipers have keeled scales while others have smooth scales. All viperids have a pair of relatively long solenoglyphous (hollow) fangs that are used to inject venom from glands located towards the rear of the upper jaws, just behind the eyes. The left and right fangs can be rotated together or independently.

- The viper has two hollow fangs at the front of its mouth, connected to a rotating maxillary bone.
- The snake can open its mouth almost 180 degrees to strike its prey.
- Vipers can rotate their fangs together or independently, that allows them to wait till the last second to erect their fangs.
- Vipers can extend their fangs and bite without injecting venom.
Viperidae Temperament / Behavior
Compared to many other snakes, vipers often appear rather sluggish. Typically, vipers are nocturnal and ambush their prey, though some could forage actively. The foremost vital determinant of venom expenditure is mostly the dimensions of the snake; larger specimens will deliver way more venom. Long fangs permit vipers to strike deeply into tissues to cause severe necrosis. In predatory bites, factors that influence the quantity of venom injected include the size of the prey, the species of prey, and whether the prey item is control or free. The need to label prey for chemosensory relocation once a bite and release may also play a task.
Feeding for Viperidae
Vipers feed on a variety of small animal prey including small mammals, rats, mice, lizards and birds.
