Penguins are flightless birds that live near the coasts of South America, South Africa, Australia, New Zealand, and Antarctica. There are 17 different types of penguins that vary in size, from the largest emperor penguins that live in Antarctica, to the smaller little blue penguins of Australia. Penguins survive in cold climates by eating fish, squid, and krill from the sea, and keeping warm by huddling together in groups.
