Penguin (scientific name: Spheniscidae): Penguin, known as the "boat of the sea", is one of the oldest swimming birds. They probably settled in Antarctica before the earth put on ice armor. There are 18 species of penguins in the world, most of which are distributed in the southern hemisphere. Mainly living in the southern hemisphere,
It belongs to Penguin, Penguinidae. Characterized by inability to fly; Feet are born in the lowest part of the body, so they are upright; There is webbed toes; Foot flexibility (other birds land on their toes); Forelimbs have fins; Feathers are short to reduce friction and turbulence; There is a layer of air between the feathers to keep warm. The back is black and the abdomen is white. The main differences between species are head color and individual size.
Penguins can survive and reproduce in the cold of MINUS 60 degrees. On land, it is like a western gentleman in a tuxedo, staggering, stumbling and flustered when in danger. But in the water, the penguin's short wings become a pair of powerful "paddles", and the swimming speed can reach 25-30 kilometers per hour. You can swim 160 km in one day. Mainly feed on krill, squid and small fish.
1488, Portuguese sailors first discovered penguins at the Cape of Good Hope near South Africa. But it was the historian Pigafetta who first recorded penguins. 1520, he took Magellan's fleet and met a large group of penguins on the Patagonian coast. At that time they called them nameless geese. Most of the penguin species described in the early days lived in the south temperate zone. It was not until the end of18th century that scientists identified the names of six species of penguins and found that the species that really lived on the Antarctic ice sheet were in19th century and 20th century. For example, the emperor penguin is only named at 1844, and the island yellow-browed penguin is only named at 1953. Penguins are obese, formerly known as obese birds. However, because they often stand on the shore and look out as if expecting something, people call this fat bird penguin. And because the front of the penguin is very similar to the word "enterprise" in China, it is called penguin in translation. ,
