What do penguins eat ?
In general, penguins eat fish (anchovies, antarctic silver, herring), krill, shrimp, squid and various molluscs. Living in one area, different species can eat in different ways. For example, the imperial and the Adélie penguin give preference to krill, while other species eat fish more readily. Species with more mollusks and crustaceans in their diet need regular food. To catch enough krill they have to dive from 190 to 860 times a day and spend a lot of energy and energy on it. Catching fish for the penguin is not difficult, its sky and tongue are seated with backed spines, which makes it easy to keep prey.
During the incubation period, some species of penguins are forced to starve. In imperial penguins, this period lasts longer than the rest of the penguins, only 2 to 3 months. Crested and penguins Adele were luckier, they were starving for 1 month. The males are hatching the chicks. Hatched chicks male imperial penguin feeds “milk” – a special nutrient from the stomach. Soon after incubation, females return to the colony. In a stretching struma, each carries about 1 kg of kashi from krill to feed the hatched offspring. Then the female finds her husband by voice and feeds the baby. The male hands the baby to his mother, and himself, who has lost 40% of his weight, goes to feed, returns from it after 1-1,5 months.
Males and females of other species (donkey, gorgeous, small and subarctic penguins) change each other constantly. This enables them not to starve during the incubation period.
