There are at least 18 different kinds of penguins. Adelies and Emperors penguins can stay alive in cold weather longer then any other animal in the world. This is the same as the fastest human runner, and four times as fast as the fastest human swimmer. Penguins can swim almost as fast as the Bottlenose Dolphin. Penguins get all of their food from the ocean.
Penguins dive deep for their food.
They eat squid, fish, and krill. Penguins enemies are the Sea Lions, Fur Seals, and the Killer Whales. The most dangerous enemy is the Leopard Seal. The Leopard Seal eats about 15 penguins a day. Usually Leopard Seals only catch the weak or the very sick.
