This venomous water snake will gape its mouth open showing its cotton white lining. Active by night, they bask in the sun during the day. Heat-sensing pits on the heads help locate prey for striking. Found in rivers, swamps and marshes they float with their heads out. Babies hatch from eggs inside the mother before being laid.
