Lachesis malabaricus

Lachesis malabaricus, commonly known as the Malabar Pit Viper or Malabar Lancehead, is a venomous snake species found in parts of India and Sri Lanka. With its striking appearance and potent venom, this serpent is a fascinating and often feared resident of the lush forests and rocky terrains it inhabits. Scales in 21 or 23:21:15 or 17 rows. Ventrals 143-158 in males and 136-159 in females.

ECOLOGY

BEHAVIOR:

Lachesis malabaricus is a nocturnal snake, meaning it is most active during the night. They are well-adapted to their dark forest habitat and have specialized heat-sensitive pits between their eyes and nostrils that help them locate warm-blooded prey in low light conditions.

AMBUSH PREDATORS:

Malabar Pit Vipers are ambush predators, meaning they wait for their prey to come close before striking. They use their excellent camouflage to blend into their surroundings, often hiding among leaves or rocks, making them difficult to spot by both prey and predators.

DIET:

These vipers mainly feed on small mammals, such as rodents, as well as birds and other reptiles. They have long, hollow fangs to inject venom into their prey, which immobilizes and aids in digestion.

VENOMOSITY (SNAKES)

Lachesis malabaricus is venomous, and its venom is potent.

GENERAL HABITAT

Malabar Pit Vipers are primarily found in forested regions, including tropical rainforests, evergreen forests, and moist deciduous forests. They are often associated with hilly and rocky terrains, but they can also be found in lowland areas near water bodies.
