Pygoscelis papua, commonly known as the Gentoo Penguin, is found on sub-Antarctic islands. Notable for its bright orange-red bill, white head stripe, and long tail, it is the fastest underwater swimming penguin. Gentoos form large colonies and are known for their playful behavior and distinctive honking calls.

Pygoscelis papua, commonly known as the Gentoo Penguin, is native to the Antarctic region. It is primarily found on sub-Antarctic islands and the Antarctic Peninsula. Key locations include the Falkland Islands, South Georgia, Kerguelen Islands, and Heard Island. Smaller populations are also found on the South Shetland Islands and the South Orkney Islands.

Gentoo Penguins inhabit areas with cold oceanic climates characterized by highly variable and often harsh weather conditions. These regions typically have temperatures that range from -10°C to 4°C. The environment is often windy and snowy, with sea ice present in more southerly regions during colder months.

The ecological niche of the Gentoo Penguin involves coastal regions where they can access the ocean for feeding. They prefer rocky shores, beaches, and open areas for nesting. Gentoos feed on a diet consisting mainly of krill, fish, and squid, which they hunt during shallow dives. Their strong swimming abilities adapt them well to their marine environment, and they are known for their relatively fast swimming speeds among penguins.
