WebPenguins present on the outskirts of the huddle don’t get much warmer compared to the penguins inside. So huddling can prevent the loss of heat up to 50%. Coming to species of penguins, emperor penguins allows many huddles to take place because they are the species living in cold Antarctica. 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.

Males spend four months without feeding during pairing and incubation.
WebTheir stance has adapted in such way to minimize heat loss. They stand on 3 resting points: their 2 heels, and tail.
