#6. Sea Snakes

Sea snakes are poisonous snakes that live in marine environments for most of their lives. Although they evolved from terrestrial ancestors, mostly got used to waters and they can't move on land except for the genus Laticauda but only limited movement on land. Their stretchy bodies are preadapted for efficient swimming. And most species have developed paddle shaped tails that further increases their ability to move in water.These are found in warm water from the Indian Ocean to the Pacific. And like Great Barrier reefs, these are found in Austrailian waters, too.
-->Why do you think although sea snakes' ancestors are form land, now they are used to the water?
