Although all penguins are well used to for underwater hunting, this does not mean that the food they always gets easy. In this respect, American researcher G. Kuymenom with colleagues obtained very interesting data. They provide data on the three king penguins on South Georgia, which carries special sensors. In the colony, where the penguins were engaged in breeding of chicks, one of them was absent 4, the second - 6, the third - 8 days. The first in a time at sea has made 1,217 dives, the second - 488, third - 890. So many have to dive because only 10% of cases can catch prey. Approximately half of the dive was to 50 m, deeper than the rest - for the 100 and even 200 m. 

What do penguins eat - plankton, fish, mollusks and cephalopods. They get it only at sea and never use emissions. Is among the penguins almost entirely eatable species. These Galapagos and Magellan penguins, as well as the penguin Humboldt. They feed on such mass schooling fish like anchovies, sardines, mackerel and the like. Due mainly krill live Adele, Antarctic, crested and macaroni penguins. In areas with abundance of krill declines and the emperor penguin, and for the Papuan he can become the basis of nutrition. Fly species do not dive deeper than 70 meters and often limited to a depth of 20m. 

Penguins eat fish, cephalopods, and crustaceans. Drink sea and fresh water, swallow the snow. Growth of the smallest penguins - 40 cm, weight - 2 pounds. Largest - 1 meter, 15 kilograms (royal), 1,2 m, 30 - 45 pounds (imperial).

Each district based nutrition penguins are dominant species of food organisms. However, even nesting in mixed colonies of different types of diets are not the same, i.e. there are signs of food specialization. Here is what recent studies have shown the British ornithologist D. Kroksella with colleagues at South Georgia and the South Shetland Islands. Macaroni penguins from South Georgia to hunt in a zone up to 100 km, and the Papuan only 10 km from the coast. 

First catches mainly small fish and krill, and the second - largest krill and fish. The South Shetland Islands macaroni penguins' produces small krill, fish and Atlantic - a major krill. According to the calculations of the French scientists, Jean Mogen's and J. Prevost eaten all the birds of the Southern Ocean food for about 85% are accounted for penguins. Neither more nor less than it is about 47 million tons, of which more than half falls on krill and other crustaceans, and about a quarter in the squid.
