The Beaked Sea Snake (Enhydrina schistosa), also known as the Hook-nosed Sea Snake or the Common Sea Snake, is a highly venomous sea snake found in coastal waters of the Indo-Pacific region. It is notable for its potent venom and distinctive beak-like snout. Here are some key details about this species:

Physical Description:

  • Appearance: The Beaked Sea Snake has a stout body with a characteristic beak-like snout. Its coloration varies but is typically gray, olive, or brown with lighter underbelly and dark bands or blotches along its body.
  • Size: Adults usually measure between 1 to 1.2 meters (3.3 to 4 feet) in length, though some individuals can grow up to 1.5 meters (5 feet).
  • Tail: The tail is laterally flattened and paddle-shaped, aiding in swimming.


  • Geographical Range: The Beaked Sea Snake is found in the coastal waters of the Indian Ocean and western Pacific Ocean, including regions such as the Persian Gulf, Bay of Bengal, and Southeast Asia.
  • Preferred Habitat: It inhabits shallow coastal waters, estuaries, and river mouths. It is often found in muddy or sandy substrates and occasionally enters freshwater rivers.


  • Status: The Beaked Sea Snake is not currently considered endangered and is classified as Least Concern by the IUCN. However, it faces threats from habitat destruction, pollution, and accidental capture in fishing nets.
  • Protection: Conservation efforts focus on habitat preservation, reducing bycatch, and raising awareness about the ecological role of sea snakes.


  • Ecological Role: The Beaked Sea Snake plays a crucial role in marine ecosystems by controlling populations of fish and other prey species.
  • Human Interaction: Although highly venomous, bites to humans are rare and usually occur when the snake is accidentally captured or provoked. Its venom is among the most potent of all snakes, requiring immediate medical attention if a bite occurs.
