Interesting facts about the penguin

  • Although penguins belong to the biological systematics to the birds, but can not fly.
  • Penguins are optimally adapted to cold temperatures: fat layer and plumage protect the penguin from the cold. The springs trap air and form a natural insulating layer to the outside.
  • The size of penguin species increases with the chill of the habitat. The smallest penguins live on the equator and the largest penguins on the south pole. Reason is the evolutionary adaptation to the cold. A larger body means less heat loss relative to the less growing skin surface.
  • Penguins live only in the southern hemisphere. There are no penguins in the Arctic (North Pole).
  • Although penguins often breed in remote places, their brood is particularly threatened by birds (such as skuas). For this reason, eggs or hatched boys are never left alone. Both partners always take turns looking for food.
  • Penguins recognize partners and offspring reliably in the voice.
  • During the annual spring change (called Mauser), penguins can not enter the water for about 4-12 weeks. During this period, the penguins feed on their previously eaten fat layer.
  • Penguins reach a maximum speed of approximately 30km / h in the water.
  • Penguins are periodically loyal to their partners. Mostly, partnerships are entered into for several years. If the rearing is successful, the penguins stay together. If it fails several times, they are looking for a new partner.
