(Aptenodytes forsteri) is a species of penguin that is native to Antarctica. It is the largest species of penguin, growing up to 122 cm (48 in) tall and weighing up to 40 kg (88 lbs). Emperor penguins live on the ice and in the ocean, and feed primarily on fish, squid, and krill. They are also the only species of penguin that breeds during the Antarctic winter.
Emperor penguins are social animals and live in large colonies of up to 10,000 individuals. They use vocalizations to communicate and maintain social bonds. Breeding pairs will form strong bonds and remain together until the next breeding season. The female lays a single egg, which is incubated by both parents for two months. During this time, the male will fast and can lose up to one-third of his body weight. After the chick hatches, both parents will feed it regurgitated food for several months until it is old enough to hunt for food on its own.
Emperor penguins are threatened by climate change and the loss of sea ice, which impacts their ability to find food and breed successfully. They are also vulnerable to pollution, oil spills, and commercial fishing. These threats have caused their population to decline in recent years, and they are listed as a vulnerable species on the IUCN Red List.
