What are the movements and living habits of penguins?

Penguin's scientific name. (spheniscus), which is the general name of all species of the class Bird, penguin family, is one of the oldest migratory birds. Penguins usually live in the cold Antarctic where people are extremely inaccessible, and feed mainly on Antarctic krill, but sometimes squid, small fish and brachiopods.

At present, there are about 18 penguins in the world, most of which are distributed in the Antarctic region, and some live near the equator, but only emperor penguins and Adélie penguins live completely in the polar regions.

Penguins, which belong to bird animals, are the oldest migratory birds, slow walking, fast swimming, staple fish and shrimp, fixed mates, and male and female co-nurse their offspring.

Penguins are mammals that are accustomed to living in groups, are cold tolerant, and live in the Antarctic region.

Penguins do belong to a kind of animal, it should belong to a kind of animal that belongs to the Antarctic aspect, and his habit is actually to eat, sleep, sleep and eat.

Penguins are oviparous and are not mammals. Penguins are birds of the genus. The goose is called:

The Ocean Boat is a very ancient species of migratory bird. They live mainly in the sparsely populated southern hemisphere, and although they belong to the class Ornithischia, they are flightless birds. Their multi-layered scaly wings make it difficult for seawater to penetrate, and they can adapt to the cold ocean life of Antarctica, and can survive and reproduce in extremely cold areas of minus 60 degrees.

The Antarctic has a lot of land and a wide sea, which also provides penguins with abundant and abundant food**, such as small fish, krill, and so on.

Penguins belong to the family of avinichian penguins. Penguins are able to live and breed in cold climates. On land, she is like a Western gentleman in a tuxedo, walking and swaying, and falling and climbing in embarrassment when encountering danger.

But in the water, the penguin's short wings make for a powerful paddle that can swim at speeds of 25 to 30 kilometers per hour. It feeds mainly on krill, squid, and small fish.

Penguins are the collective name for all species of the class Ornithischia and the penguin family.

Habits: Mainly feed on Antarctic krill, sometimes small fish and squid. Each penguin eats an average kilogram of food per day.

Penguins belong to the family of birds, they prefer cold environments, they like to eat fish and shrimp and the like, and they like to live in groups.

Penguins have a simple, generous temperament, and are very cute. Although the penguins are extraordinary, a little arrogant, and even domineering, when people approach them, they do not look away, sometimes as if nothing happened, sometimes as if they were shy and overwhelmed, and sometimes they look around, talk to each other, and chirp. That kind of honest and somewhat silly demeanor really makes people laugh, perhaps, they rarely see people, it is a kind of curiosity.

Penguins can swim nimbly and easily in the water, but this ability may negate their ability to fly. Penguins are typical seabirds, and although they can't fly, they are super swimmers among birds. Many waterfowl swim by paddling through the water with their webbed feet, and penguins have webbed feet, but they are only used as rudders to control the direction, and the power to move forward is all by the oar-like wings that flutter their wings in the water.

Penguins swim very fast, with emperor penguins swimming about 10 kilometers an hour and white-capped penguins swimming 36 kilometers in an hour, making them the fastest of all birds. Penguins often swim dolphin-style, that is, dive for a certain distance, expose the water for ventilation, and then dive back to continue swimming. In fact, the penguin is also the champion diver among birds, having dived for 18 minutes and 265 meters underwater.

By observing seabirds that are closely associated with penguins, scientists have determined that wings adapted for flight are not suitable for diving and swimming. There have long been several theories as to why penguins cannot fly. One view is that some species have lost their ability to fly because of the lack of predators on the ground.

Another view is a biomechanical hypothesis: when a bird flies and dives, it must use its wings for two different jobs. From the assumptions of biomechanics, it is impossible to create wings that are good at both.

Penguins were once faced with an evolutionary choice, choosing to fly in the air or choose to swim nimbly underwater. Usually as the wings become more efficient when penguins are diving, their ability to fly becomes weaker. At some point, flying becomes very strenuous, so the best option is to give up flying and let the wings shrink into flippers.

Penguin order Penguin family.

Penguin (scientific name: spheniscidae): It is a common name for all species of the class Bird and Penguinidae.

Penguins, known as the "Boat of the Sea", are one of the oldest migratory birds, and they probably settled in Antarctica before the Earth put on ice armor. There are 18 species of penguins in the world, most of which are distributed and live in the Southern Hemisphere. characterized by the inability to fly; In general, a penguin's legs and knees are hidden in its belly, and its feet are born in the lowest part of its body; When the penguin stands on the ground, the patella is stuck at the joint of the femur and tibial tarsal bone, which plays a role in stabilizing the knee joint, and can also be used to position and hold the femur and tibial tarsal bone. webbed between the toes; plantar (other birds land on their toes); forelimbs fin-shaped; The feathers are short to reduce friction and turbulence; A layer of air is retained between the feathers to keep them warm.

The back is black and the belly is white. The main differences between species are the color of the head and the size of the individual.

Penguins are able to live and breed in cold climates. On land, it lives like a Western gentleman in a tuxedo, walking, swaying, encountering danger, falling and climbing, embarrassed. But in the water, the penguin's short wings become a powerful pair of "paddles", which can swim at speeds of up to 25-30 kilometers per hour.

You can travel 160 kilometers in one day. It feeds mainly on krill, squid, and small fish.

Kiss! Hello! That's the answer we've put together for you, and I hope my answer will be helpful to you! If you are satisfied, I hope you will give us a thumbs up! Here, we wish you a happy life and a happy family!

The penguin has a gentle temperament, a waddling gait, and looks silly and honest, but in fact, it is a very "intelligent" animal. Penguins climb over fences on their shoulders like a "human ladder"; It has a good ability to jump high, and sometimes in order to escape the pursuit of the halberd whale, it can jump up an ice cliff about 2 meters high.

Adried penguins are the most abundant species of penguins in Antarctica. Its face is all black, its mouth is relatively short, and there is a white circle around its eyes, which seems to have a pair of glasses, and people jokingly call it "Shi".

Some seabirds can only drink seawater and will die if they drink fresh water. Adried penguins can drink both. Adririd penguins belong to the group breeding type.

Penguin eggs are incubated for 2 months, and baby penguins grow feathers 5 months after hatching. Penguins have a nostalgic nature for their hometown, and no matter how far away they are from their habitat and breeding grounds, they have to travel thousands of miles to return to their "hometown".

Scientists once took several Adridian penguins from their breeding sites along the coast to the interior of the Antarctic continent, hundreds of kilometers away, and then stood on a high iron frame to observe the penguins' movements.

Scientists have found that the penguin's ability to orient itself is reduced on cloudy and cloudy days, so it is believed that it relies on the sun to locate itself. However, the earth is constantly turning, and the position of the sun is constantly changing, and if you only use the sun to determine your position, the penguin's walking path will become a curve, and you will not be able to return home. In fact, penguins walk in a straight line, so it is believed that penguins have a wonderful direction finding mechanism that relies on them to adjust the direction of their walking.

Penguins can't fly and are good swimmers. When walking on land, he moves awkwardly, with the soles of his feet on the ground, his body standing upright, and his tail and wings for balance. In case of emergency, it can quickly lie down, stretch its wings, and crawl forward on the ice and snow; Sometimes, you can glide quickly on snowy cliffs and slopes, using your tail and wings to get your bearings.

Penguins swim at a speed of 20 30 kilometers per hour, which is faster than 10,000 tons of giant ships.

Even faster, even faster than the fastest whaling ships. Comparable to a world diving champion, Chakijan penguin can jump more than 2 meters above the surface of the water and jump from icebergs or ice to jump into the water and dive to the bottom. As a result, penguins are excellent swimmers, divers and divers.

Penguins are known for marine zooplankton, mainly Antarctic krill.

For food, sometimes it also preys on some wrist tribes and squid.

and small fish. Penguins have a good appetite and each penguin eats an average kilogram of food per day, mainly Antarctic krill. Thus, penguins act as predators in the Southern Ocean.

plays an important role in the food chain. Penguins hunt about 33.17 million tonnes of krill in Antarctica, accounting for 90% of the total consumption of Antarctic birds and equivalent to half of the krill preyed by whales. Penguin habitats vary depending on the species and distribution area:

Emperor penguins prefer to roost on ice shelves and sea ice; Adélie penguins and Kintu penguins can live on both sea ice and outcrops in ice-free areas; Penguins in the sub-Antarctic prefer to roost on rocks in ice-free areas and often build their nests with rocks. Penguins like to live in groups, with hundreds, thousands, tens of thousands, and even more than 10,200,000 penguins.

On the Antarctic continent.

On the ice shelves, or on the icebergs and ice floes of the Southern Ocean, one can see flocks of penguins congregating. Sometimes, they line up in neat formations, facing one direction, like a well-trained guard of honor.

Waiting and welcoming visitors from afar; Sometimes they are lined up in equally distanced and spaced squares, like athletes performing in group gymnastics, and the formation is very neat and spectacular.
