The king penguin (Aptenodytes patagonicus) is the second largest species of penguin in the world – after the emperor penguin – with adult king penguins growing to nearly a metre in height. The king penguin is found inhabiting the rocky islands in parts of the Antarctic Ocean, with the geographical location being one of the main differences between the two king penguin sub-species. King penguins have adapted well to the extreme living conditions of the Antarctic and, to keep warm, the king penguin has four layers of feathering. King Penguins have 70 feathers per every square inch. The outer layer of feathers are oiled and waterproof, and the inner three layers are down feathers, which act as very effective insulation as the bitter cold.King Penguins breed on the sub-Antarctic islands, at the northern reaches of Antarctica, as well as around the Falkland Islands, and other temperate islands of the region. King Penguins primarily like to consume a type of fish called lantern fish but they will eat other things if they can't find enough of it in their habitat. The king penguin has the longest breeding cycle of all the penguin species, lasting 14 to 16 months. A female king penguin may produce a chick during alternate breeding seasons. Like emperor penguins, king penguins do not build nests. Instead, they stand upright and incubate the egg on the tops of their feet under a loose fold of abdominal skin called a brood patch. Unlike emperor penguins, king penguin parents take turns incubating the egg.
