Emperor penguins mainly live in the sea. They hunt, swim and play in the water. On the one hand, they exercise their bodies well, and on the other hand, they eat and drink enough to conserve their energy for the arrival of the winter breeding season. In winter, emperor penguins have the opportunity to go out for a walk every day, and they will take the opportunity to stretch their muscles.
The swimming speed is 6-9 kilometers per hour, and even a short-distance speed of up to 19 kilometers per hour can be achieved. Dive to about 50 meters below the sea surface, where you can easily find fresh fish in the ice sea, swimming against the current on the surface of the ocean. Then, dive and surface again to breathe, and repeat the above steps. They can also blow bubbles in the cracks of the ice to force hidden fish out.
In the hunting area, emperor penguins will repeatedly dive deep into the sea to find food. They usually dive to 150-250 meters, and the deepest dive is recorded at 565 meters. They can hold their breath underwater for 15-20 minutes. Emperor penguins usually feed on fish, shrimp and cephalopods in the sea.
Antarctic petrels and skuas are the main natural enemies of little penguins. Leopard seals, killer whales, etc. are also the main natural enemies of penguins. In addition, global warming, rising sea temperatures have led to a reduction in food and a deteriorating environment, all of which have posed a threat to the survival of penguins.
There are 45 known emperor penguin colonies in Antarctica. The report states that all of these places are threatened by melting ice. Although the number of penguins will still increase by about 10% before 2050, it will drop sharply by at least 19% thereafter. The number of penguins in two-thirds of the places may drop by more than half, with the most serious situation in the Indian Ocean in the west and the east.
