A viper is a type of venomous snake belonging to the family Viperidae. They are known for their long, hinged fangs that allow them to inject venom into their prey. Vipers are found in various habitats around the world, including forests, grasslands, and deserts. They typically have a stout body and a triangular-shaped head, which helps distinguish them from non-venomous snakes. Vipers are primarily ambush predators, relying on their camouflage to blend into their surroundings. They feed on small mammals, birds, and reptiles. Some well-known species include the Gaboon viper and the Western diamondback rattlesnake. Their venom can be potent, making them both fascinating and dangerous creatures in the animal kingdom.
