The Hump-nosed Lizard is a distinctive and ancient-looking reptile endemic to Sri Lanka. Recognized by the prominent hump-like structure on its snout and its rough, textured body, this species is a true symbol of the island’s unique rainforest biodiversity. Its cryptic coloration allows it to blend seamlessly into leaf litter and forest undergrowth.
🌎 Habitat & Distribution
🌳 Habitat
The Hump-nosed Lizard inhabits lowland and mid-elevation tropical rainforests, favoring shaded forest floors, dense undergrowth, and areas rich in leaf litter. It is highly dependent on undisturbed, humid forest environments.
📍 Distribution
In Sri Lanka, it is mainly found in wet zone forests such as Sinharaja, Kanneliya, and other rainforest regions. Its distribution is limited to areas with intact forest cover.
🦎 Behavior
Feeding Behavior
This species is primarily insectivorous, feeding on ants, termites, and other small invertebrates. It uses a sit-and-wait strategy, remaining motionless before capturing prey.
Movement & Defense
The Hump-nosed Lizard moves slowly and deliberately, relying heavily on camouflage rather than speed. When threatened, it may remain still or display defensive behaviors such as opening its mouth.
Social Behavior
Generally solitary, it is most often observed alone within its territory.
Breeding
Breeding occurs within forest habitats, where eggs are laid in moist soil. The species depends on stable environmental conditions for successful reproduction.
⚠ Conservation Status
The Hump-nosed Lizard is classified as Near Threatened, primarily due to habitat loss and forest degradation. Conservation of Sri Lanka’s rainforests is essential for its survival.
📸 My Wildscape Encounter
This remarkable reptile was observed in the Sinharaja rainforest, with the guidance of Mr. Gayan Madhushanka, who helped locate this well-camouflaged species.
Using my Canon 80D with a 400 mm lens, I captured this unique lizard in its natural environment.
The encounter emphasized the beauty of Sri Lanka’s endemic reptiles and the importance of preserving their fragile habitats.
