King penguins

King penguins are the second largest species of penguin and can grow to 3 feet tall. The animals live in Antarctica, which has an estimated population of 2.23 million pairs, and the penguins are well adapted to the extreme living conditions. The birds boast 70 feathers per square inch of their bodies and have four layers of feathering. Like most penguins, king penguins are able to drink saltwater because their supraorbital glands filter out excess salt.
