WebNov 20, 2012 · Biologists have long observed how hundreds of penguins gather together in order to resist the Antarctic temperatures of -60 F and gusts of 100 mph. Other researchers showed that the penguins move from place to place within the packed group, moving outside penguins to the warmer spots and dispersing the heat loss. WebThe dark body part of the penguin absorbs heat from the sun which helps them to remain warm. The gland near the tail provides a coat of oil to feathers to increase their water-resistant power. Feathers are not much helpful underwater because the temperature of the sea is -2.2 0 C, so it is difficult to waterproof.
