Answer:
Sea snakes have flattened tails for swimming, allowing them to swim faster than if they had the tail of a regular snake. The flat shape of the tail reduces drag, as well as providing a larger surface to push the water with. However, this makes moving on land difficult. They also have valves over their nostrils that close underwater. This prevents water from entering their nose as they swim. Sea snakes have very strong venom that they use to kill their prey. They also produce an enzyme that starts digesting the animal as soon as it takes the first bite. Their diet consists of mostly fish, crustaceans, and eggs. The venom and enzyme results in little room for their prey to escape, making it easier for the sea snake to sustain itself.
