Sea Snakes (Family Elapidae, Subfamily Hydrophiinae): South-east Queensland

These snakes are related to the land elapids. Their paddle-shaped tails and laterally compressed bodies are superb adaptations to life in the sea. Sea snakes, like all reptiles, are air-breathers and must surface regularly. The nostrils, positioned on top of the snout, are sealed by valve-like flaps when diving. Most sea snakes eat fish or their eggs. All are front-fanged and venomous.

Of the 34 known Australian species, 11 have been recorded from Moreton Bay. Arranged here in alphabetical order by scientific name.
