About Crestless lizard
The Crestless Lizard
The Crestless lizard, scientifically known as Calotes liocephalus, is a species of agamid lizard native to Sri Lanka. It is also recognized by common names such as the spineless forest lizard and the lionhead agama. This species is one of four Calotes lizards endemic to the island, sharing certain characteristics like a relatively short head and swollen cheeks.
Description and Camouflage
Adult Crestless lizards typically measure around 91 mm (3.6 inches) in snout-to-vent length, with a total length reaching up to 33 cm (13 inches). A distinctive feature is the absence of spines above the ear, which sets it apart from other Calotes species and gives it its name. Its body is adorned with a cryptic pattern of indistinct stripes in pale moss-green, dark green, and brown, which extend down to the belly. The limbs and tail feature rings of pale moss-green and dark brown to black. This coloration is crucial for its survival, allowing it to blend seamlessly with its arboreal habitat and evade predators.
Ecology and Behavior
The Crestless lizard is highly arboreal, spending most of its life in treetops and very rarely descending to the ground. It is a diurnal species, meaning it is active during the day. In terms of reproduction, it is oviparous, with females laying clutches of 5 to 6 eggs.
Diet
The primary diet of the Crestless lizard consists of insects and other small animals. While insectivorous and carnivorous, some adult individuals have been observed to supplement their diet with plant matter.
