What are the characteristics of penguin wings?

Penguins have relatively short wings, and the hair on the surface is very dense, which can keep out the cold and can be used for swimming, providing power for themselves. Secondly, penguins' wings are not like those of flying birds, which can help penguins maintain balance. In addition, penguins will replace their feathers on their bodies when they grow up, in order to better incubate eggs.

Penguins have relatively short wings because the hair on the surface of their wings is very dense and has a cold-resistant effect, which is mainly used to help them swim. When penguins swim in the water, their wings are fin-shaped, which can provide power to the penguins.

Secondly, penguins' wings cannot be bent like those of flying birds, because penguins' wings are relatively hard and very smooth, which can help penguins maintain balance, after all, penguins' bodies are relatively bulky.

In addition, after penguins reach adulthood, they will replace all the feathers on their bodies, especially the feathers on their wings. The purpose of replacing feathers is to allow penguins to better incubate eggs and give birth to the next generation.

Penguins are typical seabirds. Although they cannot fly, they have strong swimming skills among birds. Many water birds swim by sliding their webbed feet in the water. Although penguins also have webbed feet, they only use them as rudders to control direction.

There are 18 independent species of penguins. The largest species is the emperor penguin, which is about 1.1 meters tall and weighs more than 35 kilograms on average. The smallest penguin species is the little blue penguin (also known as the fairy penguin), which is 40 centimeters tall and weighs 1 kilogram.

Penguins feed on marine plankton, mainly Antarctic krill, and sometimes also prey on some brachiopods, squid and small fish. Penguins have a good appetite, and each penguin can eat an average of 0.75 kg of food per day, mainly Antarctic krill.
