Penguins live in the wild on every continent in the Southern Hemisphere. But since they naturally live near cold ocean currents, the only penguins to be seen in the North are in zoos.
Four species of penguin are endangered, but some of the others might be if we don't stop global warming and the melting of their ice shelves. There are 17 penguin species:
Rockhopper Penguin (endangered)
Snares Island Penguin
Erect-Crested Penguin (endangered)
Yellow-Eyed Penguin (endangered)
Galapagos Penguin (endangered)
There is a movie about Emperor Penguins named March Of The Penguins. It is about how they breed. They have to march 70 miles to the Adelie coast. Then, (if the female gets a mate), she lays a single egg, taking almost all of her energy. She then goes to sea to eat again, leaving the male on the ice to guard the egg. The egg has just hatched when the female comes back, and the male goes to sea. The penguins huddle in "turtles" to keep warm.
Penguins eat fish, squid and krill, and are preyed upon by leopard seals and giant petrels. They have been noted to use sign language to communicate with each other. They have glands which get filled with salt, and they crash their beaks against a boulder to empty them (largely because they drink saline water). Emperor Penguins live 20 years. They first evolved during the Eocene epoch.
Recently a man was lucky enough to capture an all-black penguin on film at National Geographic.
