Menu for penguins!


Penguins are animals that live in very cold parts of the earth so they need to eat things that are pretty cold; they basically eat krill (a shrimp), squids, and small fishes. The preference of food depends of the penguin species, but is almost the same. For example the penguins that live in the northern part use to eat more small fishes than penguins in other regions.
Emperor and king penguins prefer eat squids and fishes.
The quantity of food penguins eat depends of variety and available food and the time of the year. For example a colony of 5 million penguins may eat 8 millions kilograms of krill and small fishes daily.
The way that a penguin hunt is a mystery but many scientists think, penguins has an special ability to communicate and for see in completely darkness, because most of times penguins hunt in the night. But in hard times penguins need to swim long distances in order to find food. Emperor penguins that are a big penguin need to travel up to approximately 1,500 kilometers in a single foraging trip to find and hunt food for survive.



Penguins also have a period called fasting where penguins has they annual molting periods so they eat less food, during this period penguins are develop new plumage to became adults and this process end once the molt is complete, sometimes this process is very complex for some penguins that stared very young, but there are other penguins that adapt to this process very quick. This process may be complete in a period of 60 to 120 days depending also to the weather and external conditions of each penguin. In the process the penguin create a layer to protect the upper pair of there body that would help them for the whole life.
