Penguins live in the South Pole. Penguins belong to marine birds and are typical seabirds. They usually live south of the equator and can only be seen in inaccessible places. Penguins don't like hot weather. They are only happy in cold climate. Therefore, in the distant cold ocean along the coast of Antarctica, there are the most penguins. There are 18 species of penguins in the world, most of which live in the southern hemisphere.

Penguin is a general term for all Penguinidae species. Known as the "boat on the sea", the penguin is one of the oldest swimming birds. They probably settled in Antarctica before the earth put on ice armor.

Penguins can live and breed in cold climates. 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.

Penguins feed on marine zooplankton, mainly Antarctic krill, and sometimes they prey on brachiopods, squid and small fish. Penguins have a good appetite. Each penguin can eat an average of 0.75 kg of food every day, mainly Antarctic krill.
