Sea snakes are poisonous snake species that can be found in the tropical waters of the Indian and the western Pacific Ocean. They cannot be found in the Caribbean, the Atlantic, nor the Red Sea.

A few sea snake species can also be found in the waters of Oceania.

Sea snakes are primarily part of the elapids group of snakes, which according to science, have evolved from a species of Australian snakes that lived on land.

Given that they have lungs, and not gills, which is why they must come off for air to breath, they are considered fascinating species that live in the water.

It is the reason why they live in shallow waters, and cannot live in certain parts of the ocean, such as the Atlantic and Caribbean.

They feed off eels, fish and their eggs and their lungs supports them to swim as far as 160km in the sea.

Sea snakes are venomous and are often warned about when entering the water, as many of these species are related to the cobra and land kraits. Their venom is thus very potent, making it toxic to anything it encounters.
