Green Water Dragon Introduction: The Green Water Dragon is a large tree lizard that often lives on tree trunks and in bushes beside rivers. Its belly is white or yellow, its back is green, and there are stripes running through its body. The green water dragon has well-developed and sharp nails on its limbs. Its tail can propel its body forward in the water, maintain its balance when climbing, and is sometimes used as a whip. Green water dragons are also good swimmers and can sometimes dive into the water for up to 25 minutes. In a group, there are many female green water dragons, but there is only one dominant male, and he drives other males away.
