About Phelsuma andamanense
Phelsuma andamanensis: The Andaman Day Gecko
The Andaman day gecko, scientifically known as Phelsuma andamanensis, is a distinctive species of gecko native to the Andaman Islands of India. This small, slender lizard is easily recognizable by its vibrant bright green coloration, often enhanced with red dots and stripes along its back. A notable characteristic is the bluish or turquoise tail found on males. Its range has recently extended to include the Nicobar Islands, likely due to human introduction.
Habitat and Distribution
Phelsuma andamanensis is primarily found in lowland areas within the Andaman Islands. It exhibits a generalist lifestyle, frequently inhabiting domestic gardens and thriving on various plants such as coconut palms, screw pines, and banana trees. It has also been observed living on local huts, demonstrating an adaptability to environments influenced by human activity. This adaptability has contributed to a significant population expansion, making it a rare example of an island-endemic reptile benefiting from anthropogenic changes.
Behavior and Reproduction
Despite its generalist nature, the Andaman day gecko is characterized by its shy disposition. However, this shyness is contrasted by a notable trait: extreme aggression towards other members of its own species. Reproduction typically involves the female laying two eggs in a secure, elevated location. The species is known for its fertility, with documented instances of multiple clutches being laid over relatively short periods.
