Penguins keep warm by huddling together to share body heat and cut down on the wind chill. For the penguins on the outside of the circle to keep warm, the penguins continually shuffle in a wave-like movement. The back penguins move toward the middle, while the middle penguins move outward.Know More
One way penguins stay warm is through a thermal convection process. For example, emperor penguins' feathers help to move warmer air toward their bodies. In addition, the low temperature of emperor penguins' feathers helps to insulate the penguins' bodies from the cold air.
They also stay warm through biological adaptations. For instance, the feathers of the Adelie penguin cover the nose to keep in heat. Black feathers also help absorb heat from sunlight.
Penguins lose only 20 percent body heat in cold air because of an adaptation in their nasal passages that allows them to recapture their own body heat. Some species of penguins have a layer of body fat that acts as insulation against cold, especially those penguins that spend a large amount of time in the water or in colder climates. Penguins also tuck their heads and flippers into their bodies to keep all available heat in the body.Learn more about Penguins
Contrary to popular belief, penguins do not live at the north pole or anywhere in the northern hemisphere, including Alaska. According to the Mother Nature Network, penguins live only in the southern hemisphere with large numbers of them living in Antarctica but not at the south pole itself.Full Answer >
Penguins do have knees, but they are covered in feathers, so they are not visible. A penguin's leg has four parts: the short femur, knee, tibia and fibula.Full Answer >
Because penguins are an endangered species, the U.S. (and many other countries) have strict laws regarding importation, sale and ownership. It's generally prohibited for private parties to own penguins.Full Answer >
Penguins primarily communicate vocally, but they also communicate through body language and posturing. Penguins all look virtually identical, which makes individual recognition very difficult. To overcome this, penguins have evolved different sounding voices and the ability to recognize the individual voices of their mates or chicks. This allows the birds to recognize and find their important conspecifics amid the masses, which all look the same.Full Answer >
