How do you identify a Sea Snake in the wild?

Look for key diagnostic marks including Paddle-like flattened tail for swimming, Valved nostrils, Smooth scaled body adapted to water. A representative Indo-Pacific “true” sea snake (Hydrophiinae). Olive sea snakes and related marine elapids have potent venom but are generally not aggressive toward divers.

What habitat does the Sea Snake live in?

The Sea Snake primarily inhabits Tropical seas, coral reefs, and coastal waters across Indo-Pacific oceans.

Neonate (Live Birth Ovoviviparous)

Born alive in membrane sac (ovoviviparous). Armed with fully functional venom apparatus and a single silent "button" rattle.

0 - 2 Weeks

🐍

Juvenile & Rattle Segment Accrual

Sheds skin 3–4 times per year. Each shed adds a new interlocking keratin ring to the rattle.

2 Weeks - 3 Years
