Knowra Yellow-bellied sea snake Yellow-bellied sea snake The yellow-bellied sea snake is a highly venomous, open-ocean snake with a dark upper body and bright yellow underside. It ranges through tropical and subtropical waters of the Pacific and Indian oceans.
Sea snake : A venomous snake adapted to marine life, with most species inhabiting coastal waters of the Indo-Pacific. This species belongs to the sea snakes, though it is unusually adapted to open-ocean life.
Pelagic zone : The open-water region of the ocean, away from the seabed and shore. Unlike many sea snakes, this species spends much of its life in the open ocean.
Yellow-lipped sea krait : A banded, amphibious sea snake that hunts in water but comes ashore to digest food and lay eggs. Unlike this permanently marine snake, sea kraits regularly return to land.
Yellow-bellied sea snake distribution : The geographic range of the yellow-bellied sea snake across tropical and subtropical ocean waters. Its broad Pacific and Indian Ocean range is exceptional among marine snakes.
Hydrophiinae : A subfamily of venomous snakes that includes true sea snakes and their terrestrial relatives, the Australasian elapids. Its classification places the yellow-bellied sea snake among true sea snakes in this group.
Oceanic dispersal : The movement of organisms across ocean waters, often aided by currents and floating objects. Currents and drifting debris can carry this snake across vast stretches of ocean.
Olive sea snake : A large, coastal sea snake that lives around coral reefs and feeds on fishes and crustaceans. Its reef-associated life contrasts with the yellow-bellied sea snake's open-ocean habits.
Yellow-bellied sea snake reproduction : The reproductive biology of the yellow-bellied sea snake, a live-bearing snake that gives birth at sea. Giving birth in water removes the need for this species to return to land.
Salt gland : An organ that removes excess salts from an animal's body and releases them to the environment. A salt-excreting gland helps it maintain water and ion balance while living in seawater.
Sea snake bite : Envenomation caused by a sea snake's bite, which can produce severe muscle injury and paralysis. Its potent venom makes bites medically serious, even though encounters are uncommon.
