Penguins are flightless birds found in the Southern Hemisphere that lay eggs and have waterproof feathers. There are 17 penguin species that live between 15-20 years. They swim using wings as flippers and can reach speeds of 10mph. Some species like the Galapagos and Emperor penguins are endangered, while others like the Blue and Macaroni are vulnerable or of least concern. In 1940, supposed sightings of a giant penguin in Florida turned out to be a hoax involving a fake three-toed creature.
