The Soa-Soa Water Lizard, or Philippine sailfin lizard, (Hydrosaurus pustulatus) is a species of oviparous lizard endemic to Philippines.

Physiology and behaviorEdit

Soa-Soas are fairly large lizards, growing up to a meter (3' 3.37") in length. They are excellent swimmers but are able to run across water in a similar manner to Basilisk Lizards thanks to flattened toes.

They display sexual dimorphism with males possessing a larger crest than females. Males will also gain a shade of violet as they age; females will remain less colorful.


Soa-Soas can be found in tropical wooded habitats close to bodies of water such as mangroves, rice fields, rivers and riverbanks. Unfortunately they are often confused for their relative, the Amboina Sailfin Lizard. This means that it has become uncertain their exact distribution.
