VIPER
Viperinae
DESCRIPTION
Viper (Viperinae) is commonly known as true vipers and includes a variety of species characterized by their long, hinged fangs that allow them to deliver venom deep into their prey. These snakes typically have a robust body and a triangular head, with many species displaying intricate patterns and colors that provide camouflage in their natural habitats. Vipers are primarily terrestrial and are known for their ambush hunting strategy, often lying in wait for unsuspecting prey to come close before striking with remarkable speed.
FUN FACTS
- Vipers have a unique method of hunting that involves using their heat-sensing pits to detect warm-blooded prey even in complete darkness
- Additionally, some species of vipers can give birth to live young, a trait known as ovoviviparity, which is relatively rare among reptiles
