Antarctic & Southern Ocean wildlife
Antarctic and Southern Ocean wildlife
Antarctica is Earth's coldest, driest continent. It has no native land mammals or reptiles; its only true terrestrial animals are tiny invertebrates such as mites, springtails, and a wingless midge. The animals most people picture here — penguins and seals — are coastal species tied to the surrounding Southern Ocean.

Featured Southern Ocean fish
A representative selection of fish recorded for Antarctica, grouped by where they live rather than as a single scientific class. Coverage is representative, not complete; each card links to a profile with source-backed range notes.
A large predatory fish of the high-latitude Southern Ocean around Antarctica, with antifreeze proteins.

Source & range methodology
- Distribution notes are cautious educational summaries drawn from the authoritative source linked on each animal — not complete range maps.
- A confidence label is shown on every record; introduced and domestic contexts are flagged, and we avoid unsupported “native to” claims.
- Captive or zoo presence is never treated as wild range, and continent membership is not a political claim about borders.
