The dog-headed sea snake is an aquatic snake up to one meter long. It lives in coastal waters and mangrove forests of Southeast Asia and swims well.
The dog-headed snake differs from other snakes by its wide head and ability to live in brackish water. It helps maintain balance in coastal ecosystems by eating fish.
Immature form that undergoes metamorphosis before adulthood.
