The difference between emperor penguins and king penguins is mainly reflected in the following four aspects:
Background: Emperor penguins live in the Antarctic continent, and the background is usually ice and snow. Emperor penguins live in the sub-Antarctic, and the background may be grass or sand.
Size: Emperor penguins are usually bigger and stronger than emperor penguins.
Head characteristics: Penguins can be distinguished by observing the mouth, color and color block shape.
Baby: The baby of emperor penguin is usually cute, but the baby of emperor penguin has no corresponding description.
Partners, to sum up, emperor penguins and king penguins have obvious differences in living environment, body size, head characteristics, baby looks and so on.
Life habits of emperor penguins:
Antarctic penguins have special morphological structure and special physiological functions to adapt to low temperature. Penguins are covered with a layer of feathers, which are divided into an inner layer and an outer layer, and the outer layer is a slender tubular structure; The inner layer is fine fluff. Both of them are good thermal insulation structures, which can not only prevent the invasion of cold air from the outside, but also prevent the heat loss of internal energy.
The villus can absorb and store weak infrared energy, which can be used to maintain body temperature and resist cold. Penguins often stand on the cold ice and snow, but their feet will not freeze, which is entirely due to the delicate physiological structure of penguins. Penguin's leg arteries can regulate blood flow according to the temperature of the feet, so that the feet can get enough blood, and then the temperature of the feet is several degrees higher than the freezing point.
The thick fat layer in penguins is about 3-4 cm, especially those with big bellies. The fat layer is the main energy for penguins to move, keep their body temperature and resist the cold. Penguins don't eat or drink when they are pregnant and hatching eggs, that is, they consume their own fat layer to maintain their lives. When emperor penguins hatch eggs, the fat layer consumes about 90%.
