How many degrees does a penguin need to survive?

Penguins rely on feathers to resist the cold. Penguin's feet are born at 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.

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.

Penguins don't like hot weather very much. They are only happy in cold climates. Therefore, there are the most penguins living in the cold ocean along the coast of Antarctica.

Extended data

Species status:

There are not many species of Antarctic penguins, but the number is considerable. According to long-term observation and estimation by ornithologists, there are nearly 65.438+0.2 billion penguins in the Antarctic region, accounting for 87% of the total number of penguins in the world and 90% of the total number of Antarctic seabirds. The largest number is Adele penguins, about 50 million, followed by crested penguins, about 3 million, and the least number is emperor penguins, about 570 thousand.

Breeding mode:

Life history changes with the size and geographical distribution of species. The reproductive cycle of the same species is also related to latitude. Some species migrate long distances to the nesting areas of inland ancestors to lay eggs. The spotted ring penguin and the little blue penguin breed twice a year, and most species breed only 1 time a year. Emperor penguins breed twice every three years.
