Enhydrina schistosa, commonly known as the beaked sea snake, inhabits coastal waters and estuaries in the Indian Ocean and surrounding seas. It is distinguished by its laterally compressed body, olive or grayish color, and a distinct beak-like snout. Notably, it is one of the most venomous sea snakes and has a crucial role in controlling fish populations.

Enhydrina schistosa, commonly known as the beaked sea snake, is primarily found in the coastal and marine waters of the Indian Ocean and the western Pacific Ocean. Its geographical distribution includes the coastal regions of countries such as India, Sri Lanka, Bangladesh, Myanmar, Thailand, Malaysia, Indonesia, and northern Australia. The species is also present in the waters of the Persian Gulf and the Red Sea.

The beaked sea snake inhabits tropical and subtropical marine environments, typically found in shallow coastal waters, estuaries, and river mouths. It prefers areas with sandy or muddy bottoms and is often found in regions with coral reefs, mangroves, or seagrass beds. The waters it inhabits usually range in temperature from 24°C to 30°C.

Enhydrina schistosa occupies a carnivorous niche, feeding primarily on fish and occasionally on crustaceans. Due to its highly venomous nature, it is an apex predator in its ecosystem. It is well-adapted to a fully aquatic lifestyle, with a flattened body and a paddle-like tail for efficient swimming. The species is also known for its ability to remain submerged for extended periods while hunting.
