Found mainly on the islands of Luzon, Mindoro, and Polillo, this semi-aquatic lizard is famous for the large sail-like crest on its tail, which gives it a prehistoric, almost dinosaur-like look. The sail is made up of tall, spiny scales that help it swim, regulate body temperature, and possibly attract mates. Its body is long and muscular, with a strong tail, sharp claws for climbing, and rough, textured skin.

One of the most impressive things about the Philippine sailfin lizard is its vivid coloration. Males are especially colorful, showing off shades of green, blue, and even purple, particularly around the head and limbs. These bright colors can intensify during mating season. Females and young lizards tend to be duller in comparison, with more muted greens and browns that help them blend in with their leafy surroundings. Adults can grow up to a meter long (over 3 feet), making them one of the largest lizard species in the Philippines.

These lizards are omnivores, meaning they eat both plants and animals. Their diet includes fruits, leaves, flowers, insects, and small animals like snails or amphibians. They are diurnal, active during the day, and are usually found near rivers, lakes, and forest streams. They are excellent swimmers and climbers — if threatened, they’ll often leap into the water and swim away or hide among rocks and roots. Despite their dragon-like look, they are shy and prefer to avoid humans.
