The King Penguin (Aptenodytes patagonicus) is the second largest species of penguin at about 90 cm (3 ft) tall and weighing 11 to 15 kg (24 to 33 lb), second only to the Emperor Penguin. There is a world population of approximately four million King Penguins, divided into two subspecies (A. p. patagonicus and A. p. halli). These populations are thought to be on the increase.
King penguins eat small fish, and squid and rely less than most Southern Ocean predators on krill and other crustaceans. On foraging trips they repeatedly dive to over 100 metres (350 feet), often over 200 metres (700 feet). King Penguins live on the subantarctic islands at the northern reaches of Antarctica, as well as Tierra del Fuego, the Falkland Islands, and other temperate islands of the region.
