Hydrophis – Sea snakes
Swimming and diving in Southeast Asian & Indo-Australian seas
Despite having the strongest venom of any snake, sea snakes rarely cause human fatalities because they are not aggressive, produce little venom, and have relatively short fangs.
Since all species must dive to the seafloor to get food, they spend most of their time in waters less than 30 meters (approx. 100 ft) deep.
They occasionally raise their heads above the water when swimming quickly. The typical color pattern of sea snakes features black bands alternated with grey, blue, or white rings. However, the hues and patterns of individual sea snakes vary widely.
