Enhydrina schistosa, commonly known as the beaked sea snake, is a highly venomous marine reptile found in the coastal waters and estuaries of the Indo-Pacific region. This species is notorious for its potent venom and plays a crucial role in marine ecosystems by maintaining the balance of fish populations.

The beaked sea snake has an elongated, laterally compressed body adapted for swimming. It typically grows between 1.2 to 1.5 meters in length. Its color ranges from gray to olive, with dark bands running along its body. The species gets its name from its slightly hooked, beak-like snout, which distinguishes it from other sea snakes.
This species is commonly found in shallow coastal waters, estuaries, and muddy seabeds from the Indian Ocean to Southeast Asia and northern Australia. It is well adapted to brackish waters and often ventures into river mouths and mangrove forests.
Enhydrina schistosa is a piscivorous predator, primarily feeding on catfish, gobies, and other small fish. It uses its powerful venom to quickly immobilize prey, making hunting in the ocean’s dynamic environment highly efficient. The snake’s fangs are short but effective in delivering venom, which acts swiftly to paralyze its target.
Enhydrina schistosa is one of the most venomous sea snakes, with venom that contains potent neurotoxins and myotoxins. Despite its lethal bite, it is not aggressive toward humans unless provoked. Its streamlined body and laterally compressed tail aid in swift swimming, allowing it to escape potential threats.
The beaked sea snake is ovoviviparous, meaning females give birth to live young instead of laying eggs. A single litter can contain up to 30 offspring, which are fully developed and capable of swimming and hunting immediately after birth. This reproductive strategy increases their survival rate in the marine environment.
As a top predator, the beaked sea snake helps regulate fish populations and maintain ecological balance. By controlling certain fish species, it indirectly supports the health of marine food webs and prevents overpopulation of specific prey.
Although not currently listed as endangered, Enhydrina schistosa faces threats from habitat degradation, bycatch in fishing nets, and water pollution. Conservation efforts focus on protecting marine habitats and minimizing human-wildlife conflict.
Enhydrina schistosa, the beaked sea snake, is a fascinating yet formidable marine reptile. Its venomous nature, unique adaptations, and ecological role make it a key species in coastal environments. While it poses a potential risk to humans, it remains an essential component of marine biodiversity, emphasizing the need for conservation and responsible coexistence.
