Swims with its body underwater and only its snake-like neck above the surface. Feathers aren't waterproof.
- Populasi
- Not numerically quantified; population size is unquantified and current trend is "stable" (suspected to fluctuate with wetland habitat conditions)
- Habitat
- Freshwater and brackish wetlands, lakes, rivers, swamps and sheltered coastal waters, typically more than 0.5 m deep with fallen trees, logs, or vegetated banks for perching and wing-drying; occasionally inland saline waters
- Fakta menarik
- Nicknamed the "snakebird" because it swims with its body submerged and only its long, slender, kinked neck visible above the water, giving it a serpentine appearance; a banded individual was once recovered 2,431 km from its banding site.
- Sebaran
- Australia (widespread except the driest interior deserts — Great Sandy, Great Victoria, Nullarbor — and only an uncommon vagrant to Tasmania), New Guinea, Indonesia (Moluccas, Lesser Sunda Islands), New Britain, and Timor-Leste; vagrant records also occur in New Zealand. Extent of occurrence ~13.1 million km²

New Guinea snake-necked turtle), freshwater shrimp, aquatic insects, and other invertebrates
