About the Bengal Monitor Lizard
The Bengal monitor is a large lizard species that can reach 5-6 feet in length. It has a muscular build, powerful claws, and a long, forked tongue that it uses to sense its environment. Bengal monitors are highly adaptable — they climb trees with ease, swim across villus, and dig extensive burrows. They are opportunistic predators, feeding on anything from insects and eggs to small mammals and carrion.
Wilpattu Significance
Bengal monitors are one of the most commonly seen reptiles in Wilpattu. They are frequently observed crossing roads, climbing trees, or basking in the sun at the edge of villus. Their presence is a sign of a healthy ecosystem. During the breeding season (June-August), males engage in impressive combat — rearing up on their hind legs and wrestling for dominance.
Conservation Status
Least Concern. Common throughout Wilpattu and Sri Lanka's dry zone.
Best Season to See
Year-round. Most active during the warmer months (March-October).
