There are many different kinds of penguins — 17 to 19 species, to be more precise.
Depending on the species, a wild penguin can live 15 to 20 years. During that time, they spend up to 75 percent of their lives at sea.
Penguins’ eyes work better underwater than they do in the air, giving them superior eyesight to spot prey while hunting, even in cloudy, dark or murky water, or where water is turbulent.
The world’s largest museum is the ocean. Underwater you can find relics, artifacts, ruins, and shipwrecks that number more than what you can find in the world’s museums combined.
