Penguins catch their food while swimming in the ocean. Penguins primarily eat fish, squid and krill that they catch with their sharp beaks. Over their evolutionary history, the ancestors of modern penguins lost their ability to fly in exchange for becoming extraordinary swimmers.Continue Reading
Penguins are among the most skilled fish-eating animals in the world, which is necessary to fuel their high caloric needs. In contrast to fish who need relatively few calories to drive their cold-blooded metabolisms, penguins must eat a lot to heat their bodies internally. Penguins' maneuverability in the water has come at the cost of not only flight, but also gracefulness while walking. Some species engage in a practice called “tobogganing” in which they lie on their bellies and slide from place to place.
There are 17 species of penguins in the family Spheniscidae. While the various species exhibit a great deal of variation, all of them live alongside the oceans and seas of the Southern Hemisphere. Most penguins form very large groups that may contain thousands of individuals. However, penguins are monogamous animals that bond strongly with another individual. Many species have evolved elaborate mating rituals or displays to help individuals stand out from the crowd.Learn more about Penguins
Penguins generally eat fish, squid and krill, though their diet depends on the species. Generally, penguins living close to the equator eat more fish, while penguins in arctic climates rely on squid and krill for sustenance.Full Answer >
Penguins move by shuffling their feet from side to side when on land and by using their flippers, tails and a bubble mechanism to swim in the water. The speed of the penguin in both walking and swimming will depend on the species of penguin as well as the size of the penguin.Full Answer >
Penguins sleep on both land and as they float at sea. It is not unusual for penguins to sleep standing up, although they also sleep laying down.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 >
