Banded Sea Snake

About Banded Sea Snake

The Banded Sea Snake, also known as the Yellow-lipped Sea Krait, is one of the most commonly encountered sea snakes in tropical Indo-Pacific waters. Recognizable by its distinctive black and white or bluish-grey bands, this semi-aquatic reptile splits its time between land and sea. Unlike most sea snakes, Banded Sea Snakes must return to land to digest food, lay eggs, and shed their skin. They are docile and rarely aggressive toward divers, despite possessing highly potent neurotoxic venom. Massive aggregations of hundreds of individuals can be found at volcanic islands like Manuk in the Banda Sea.

Quick Facts

• Habitat: Coral reefs, rocky coastlines, and volcanic islands in the tropical Indo-Pacific. Found from the Bay of Bengal to Fiji. Prefers shallow reef flats and lagoons for hunting, but returns to land for resting and egg-laying.
• Diet: Primarily eels, especially moray eels and conger eels. Also feeds on small reef fish hiding in coral crevices.
• Best season: September to November (peak aggregation season in the Banda Sea). Year-round encounters possible throughout Southeast Asia.
