The sea snake is a marine reptile found primarily in warm coastal waters of the Indian and Pacific Oceans. They are known for their elongated bodies and paddle-like tails, which help them swim efficiently. Sea snakes are highly adapted to life in the ocean, with many species being able to hold their breath for long periods while hunting for fish and other prey. These snakes are generally non-aggressive but can be venomous, with some species possessing potent toxins. Despite their venom, sea snakes are not typically dangerous to humans unless provoked. They play an important role in marine ecosystems by controlling fish populations.
