Penguins and ducks have webbed feet. What's the use of this foot for them?

This is in line with their living habits. For example, birds' claws can help them grasp the trunk, and ducks' webbed feet can let them swim in the water, which is suitable for living in the water.

Ducks have fin fan feet between each finger, which is more conducive to paddling.

Duck feet Generally speaking, if objects with different temperatures are close together, the final temperature will become the same, which is also a kind of balance. When it comes to ducks, the first thing to understand is that the blood flowing through the feet comes from the heart of ducks. As the core of the body, the temperature of duck heart is about 40℃. When the warm feet of blood enter the river near the freezing point, the temperature difference between them will make the blood lose energy. If the cooled blood continues to circulate in the body, it will inevitably produce a temperature difference with the whole body of the duck, so the temperature of the whole duck will drop. Ducks can slightly limit the amount of blood flowing to their feet, but this does not completely solve the problem.

Penguins have feet, which play a great role. Their feet are shaped like duck fins, which can help them "fly" in the water. Penguin's feet are basically similar to those of other birds, but their bones are harder than those of other birds, and their feet are short and flat. This feature is like the short wings of two paddles, allowing penguins to "fly" quickly underwater. Moreover, when penguins walk slowly in the snow, they use webbed feet as sledges and move quickly in the snow.

Penguin is the symbol of the South Pole. These "Antarctic gentlemen", who are cocky, stumbling and wearing tuxedos, have thrived in this mysterious land of Antarctica for thousands of years.

Penguin can be said to be an ancient bird, which settled in Antarctica before it was covered with ice armor. With the change of Antarctic climate, penguins have developed a set of skills to resist cold and snow. They either walk in the snow or swim in the cold sea. They have an indissoluble bond with ice and snow.

Because of this, penguins mainly live in the Antarctic continent and South shetland islands, but also spread northward with the cold current, reaching south latitude 17 degrees in Africa and 38 degrees south latitude in Australia, and some species can extend to the equator in Latin America. Penguins are found in the southern coastal islands of South Africa, the southeast coast of Australia, the west coast of New Zealand and even the Galapagos Islands near the equator of Ecuador.
