Penguins are flightless birds that live in the Southern Hemisphere. Few species of penguins like emperor penguins live in the real cold of Antarctic islands where the temperature never rises above the freezing point. Many of us may wonder how these flightless birds live in the icy marine world. Nature has built their body to adapt the cold easily.
Although nature has provided the body mechanism to work without the effort of penguins, there are also steps that penguins take to survive the cold. Penguins are excellent swimmers and divers. Gentoo penguins can swim at the speed of 22 mph and emperor penguins can dive to the depth of 1,700 feet.
Penguins are social birds that like to be in the colonies especially during the breeding season. When the penguins molt, they avoid being in the cold since they shed their old feathers and wait for the new ones to cover the body.
