Asian Water Dragon

Physignathus cocincinus

Also known as Chinese Water Dragon, Indochinese Water Dragon, Thai Water Dragon, Green Water Dragon

Asian water dragons spend their days draped over tree branches hanging directly above tropical streams, plunging into the water at the first sign of danger. Males display vibrant green scales, bright yellow or pinkish throat patches, and high spiky crests running along the neck and back. Their long, powerful tails make up two-thirds of their body length and propel them smoothly through forest waterways.

Responsible observation
  • Scan Overhanging Branches: Search for green silhouettes resting on foliage above shaded forest streams.
