Philippine Sailfin Dragon (Hydrosaurus pustulatus)

Hydrosaurus pustulatus, commonly known as the Philippine sailfin dragon, is a large, semi-aquatic lizard native to the forests and riverbanks of the Philippines. It is famous for its striking sail-like crest running along its back and tail, which is more pronounced in males and used for display during territorial and mating behaviors. This species has rough, keeled scales and a long, muscular tail adapted for swimming, as it often escapes predators by diving into water. Hydrosaurus pustulatus is primarily herbivorous but may occasionally consume insects and small animals. Its vibrant appearance and unique behaviors make it a fascinating species within the agamid family, well adapted to both terrestrial and aquatic environments.
