Penguins are a kind of birds. They are a special kind of birds. They have a very strong ability to resist the cold, especially penguins born in the Antarctic region. Sometimes they are still in the water, and they are not afraid of the cold sea water. Hibernation is a habit of some animals, which is used to keep out the cold in winter. Animals with hibernating habits are basically poikilotherms, that is, animals whose body temperature is not constant, and from an evolutionary point of view, they are relatively low animals. Penguins do not hibernate and do not have the habit of hibernation.
From an evolutionary point of view, penguins are birds, not as advanced as mammals, but they are already second only to mammals. Therefore, from the point of view of the characteristics of body temperature changes, they belong to warm-blooded animals, and their body temperature will not change with the changes of the external environment. Whether in winter or in other seasons, the body temperature of penguins is constant, and they do not need to hibernate to survive the winter. In addition, the ability of penguins to resist the cold is very strong, and they do not need to hibernate to resist the cold. For example, penguins have thick feathers and thick fat layers, which are enough to resist the cold.
? As mentioned above, penguins are warm-blooded animals, and their ability to keep out the cold is very strong. They do not need to hibernate to survive the winter. Penguins belong to birds, most birds can fly, but the ability of penguins is not particularly strong. In addition, most penguins do not have the ability to climb trees. Because many penguins live in Antarctica, few trees can be seen in Antarctica, and penguins living here for a long time have no chance to exercise their ability to climb trees. However, some penguins live in temperate areas where trees grow. These penguins sometimes move in trees, but their ability to climb trees is not as good as other animals that are good at climbing.
