Where is the penguin's home?

Penguins mainly live in the Southern Hemisphere. There are 17 or 18 known species of penguins in the world, most of which are distributed in the Antarctic region. Among them, the Humboldt penguins, Magellanic penguins and black-footed penguins of the genus Spheniscus are distributed in temperate regions with lower latitudes, while the Galapagos penguins are distributed closer to the equator. Only emperor penguins and Adélie penguins live completely in the poles.

What color are penguins?

The penguins we usually see are mainly black and white, with black backs and white chests and abdomens. But penguins are not only black and white. There are 18 species of penguins in the world, most of which are distributed in the Southern Hemisphere. They mainly live in the Southern Hemisphere and belong to the order Spheniscus and family Spheniscidae. They are characterized by being unable to fly; their feet are born at the lowest part of the body, so they have an upright posture; there are webbed feet between the toes; they walk on their toes (other birds land on their toes); their forelimbs are fin-shaped; their feathers are short to reduce friction and turbulence; a layer of air is retained between the feathers to keep warm. The back is black and the abdomen is white. The main difference between the species is the head color and individual size.

Emperor penguins have bright yellow and bright orange feathers around their eyes and on their necks; king penguin chicks have lighter yellow ear spots and darker jaw plates, which are brown in color; yellow-eyed penguins have a yellow stripe on their heads; Adélie penguins have a blue-green head; and Cape penguins have orange decorative feathers connected left and right between their eyes.

Why are penguins cold-resistant?

1. Penguins are one of the oldest migratory birds. They may have settled in Antarctica before the continent was covered with ice.

2. Although Antarctica is extremely cold, penguins have been tempered by snowstorms for tens of millions of years, and their feathers have become overlapping and closely connected scales. This special feather coat is not only difficult for seawater to penetrate, but also impossible to break through its thermal insulation defense line.

3. Antarctica has a lot of land and a wide sea, and the rich marine plankton has become a plentiful source of food for penguins. Penguins are birds, so they don't have teeth. Penguins have barbs on their tongues and upper jaws to adapt to swallowing fish and shrimp, but these are not teeth.
