Philippine Sailfin Lizard

The Philippine sailfin Lizard is an excellent swimmer and has flattened toes that enable it to run across water. It is omnivorous, feeding on fruit, leaves, flowers, insects, and small animals . It lives near rivers in the tropical forests of the Philippines. Males have a larger crest on their back than the females. The males also show a violet color as they grow older. Females are less colorful.
The Philippine sailfin lizard lives mainly beside water, e.g., rivers, riverbanks, rice-fields, etc., as these lizards love to swim. The adults may reach up to a metre in length. Due to confusion with H. amboinensis, the exact distribution in the Philippines is uncertain, but northern populations are generally considered H. pustulatus and southern considered H. amboinensis.
