In fact, the earliest penguins were seabirds that could fly, but in order to adapt to the environment, their wings slowly evolved into fins that they could swim in water. The Magellanic penguins we see here are the largest penguins in temperate regions. They were first discovered in 1519 by the famous navigator Magellan, so the later scientists named the penguin after him. They are social animals and can drink seawater directly and expel salt from their bodies through their body glands. They have no special preference for feeding, and mainly feed on fish and shrimp. There are 18 species of penguin in the world, the largest is the emperor penguin, height and weight can reach the standard of a 6-year-old child. The smallest is the little blue penguin, also known as the fairy penguin, which measures only 30 centimeters in length. The original meaning of “qi” in Chinese is “standing with heels”. When the penguin stands like a human, it always seems to be looking forward to something, so it is named “qi e” in Chinese. And because of its color, much like wearing a tuxedo, so it is also known as the “Antarctic gentleman”. Honed by tens of millions of years of snowstorms in the cold South Pole, penguins’ feathers have become overlapping and dense. This special “raincoat” not only makes it difficult for the sea to penetrate, but also keeps the body warm even when the temperature is nearly minus 100℃.
