The Leaf-nosed Lizard, Ceratophora tennentii, is a small reptile endemic to Sri Lanka, notable for the distinctive leaf-like appendage on its snout. This fleshy, laterally compressed structure is present in both sexes, though it is somewhat smaller in females. Adults typically reach a total length of approximately 18.5 centimeters, including the tail. Their dorsal coloration ranges from reddish brown to olive green, with dark markings around the eyes and along the sides of the neck. The tail features about ten dark brown bands, and the ventral side is cream-colored.

Inhabiting the wet tropical montane cloud forests of the Knuckles Mountain Range at elevations between 700 to 1,200 meters, the Leaf-nosed Lizard is primarily arboreal and slow-moving. It spends much of its time on low branches, utilizing a sit-and-wait strategy to ambush prey. Males exhibit territorial behaviors, such as head-bobbing and body-lifting displays, to ward off rivals and attract mates. Despite its limited range, this species has adapted well to its specific habitat, relying on its cryptic appearance to blend into the forest environment.
As an insectivore, the Leaf-nosed Lizard's diet consists mainly of insects, caterpillars, and earthworms. Employing its sit-and-wait predatory strategy, it remains motionless on branches until unsuspecting prey comes within reach. Occasionally, it may descend to the forest floor in pursuit of food. This feeding behavior plays a role in controlling invertebrate populations within its ecosystem.
Reproductive information on this species is limited. Females are known to lay between two to four eggs per clutch, likely depositing them in secure locations within the forest. As with many agamid lizards, it is presumed that there is no parental care post-oviposition, and hatchlings are independent from birth. The presence of the rostral appendage in juveniles suggests it may have functions beyond reproduction, possibly related to camouflage or species recognition.
The Leaf-nosed Lizard is classified as Endangered, facing threats from deforestation, pesticide use, climate change, forest fires, and habitat loss due to agricultural expansion. Conservation efforts are crucial to preserve its natural habitat and mitigate these threats, ensuring the survival of this unique species.

The Leaf-nosed Lizard's unique nasal appendage is not used for combat or display. Its function remains a mystery, though some researchers suggest it may aid in camouflage by breaking up the lizard's outline among foliage.
This lizard is a skilled climber and primarily feeds on insects. Though it can be a bit shy, it's known to defend itself by puffing up its body to appear larger and more threatening when threatened.



The King Cobra, ophiophagus hannah, stands as the world's longest venomous snake, with adults typically reaching 3 to 4 meters in length, though specimens exceeding 5 meters have been recorded.
