About Sitana spinaecephalus
Sitana spinaecephalus: The Spiny-headed Fan-throated Lizard
Sitana spinaecephalus, commonly recognized as the spiny-headed fan-throated lizard, is a species that belongs to the agamid family of lizards. This species is endemic to India, meaning it is found naturally nowhere else in the world. Its natural range encompasses the west-central states of the country, including Gujarat, Rajasthan, Maharashtra, and Madhya Pradesh. The preferred habitats for Sitana spinaecephalus are scrublands and forests.
Description and Behavior
These are medium-sized lizards, with documented average lengths for males around 48.5 mm and females around 44.8 mm (likely snout-to-vent length). A notable characteristic of the species, particularly in males, is the use of their dewlap, a flap of skin under the throat. When disturbed or threatened, males will deploy this dewlap, likely as a visual deterrent to intimidate potential predators. This colorful appendage also plays a role in communication, especially during the breeding season, allowing males to interact with females or rivals.
Diet and Reproduction
Like many lizards within the genus Sitana, the spiny-headed fan-throated lizard primarily sustains itself on arthropods, classifying it as an insectivore. The species is oviparous, which means it reproduces by laying eggs. While specific details regarding clutch size or incubation periods are not extensively documented in available records, the oviparous nature is a key aspect of its life cycle.
