Why are penguins chubby? Does its size have anything to do with the environment in which it lives?

When the penguin hatches the eggs, the male carefully places the eggs on the instep of the flippers.

avoids direct contact with ice and covers the eggs with a thick belly. Male penguins stop eating and become completely dependent on fat for life, even if they lose a third of their body weight. Penguins are so fat, keep out the cold and breed!

But the penguins in the zoo are not fake penguins that they keep to fool tourists, but real penguins, and these penguins are really afraid of the cold. Without heaters to keep these penguins warm, these penguins would have a hard time at home. In the case of dozens of degrees below zero, the penguins we see are not afraid of the cold at all, and can still play carefree.

The penguins in the zoo are real penguins, but they are penguins from warm regions, which are somewhat different from the penguins of the polar regions. Are penguins in warm regions afraid of the cold because of their different living environments? Actually, it's not entirely true.

The reason Antarctic penguins are hardy is their unique secret. Why are most penguins not afraid of the cold? Penguins are similar to birds and also have feathers, which are three to four times denser than birds of the same size.

In fact, penguin feathers are different from bird or bird feathers because their feathers have turned into overlapping and tightly connected scales that look and feel extremely smooth and not layered like bird feathers.

They lost the ability to fly during evolution, and their wings evolved into fins, and their feet were in different positions, making their bodies erect, so they walked upright like humans. In order to adapt to swimming underwater, penguins become very short with feathers, which can reduce drag. Don't underestimate penguins because they can't fly.

They can swim at speeds of up to 30 km/h at an average speed.

Around 10 km h. All penguins that breed offspring are monogamous.

The pairing relationship of most species can last a lifetime. If one of them dies, the other will find another mate for the next breeding season. Generally, most penguin species breed only once, while emperor penguins breed twice in three years.

They mostly start breeding in the Southern Hemisphere, and penguins are likely to breed all year round. The exception to this is emperor penguins, which begin to breed in the Southern Hemisphere and generally have temperatures around -40. Not all penguins live in Antarctica, so there are significant differences in the ability of different species of penguins to withstand the cold and live on the Antarctic continent.

Penguins in and surrounding waters are more resilient to the cold. Penguin feathers have a good thermal insulation effect and can reduce the rate of heat loss in cold seawater. At the same time, some penguins can control the flow of blood to the limbs, armpits.

The veins are well developed and help warm the blood flowing back to the heart. In extremely cold conditions, penguins on land warm up in flocks and change their position in the colony by moving. Each penguin has its own optimal temperature range.

The penguin's chubby size is related to its living environment. Penguins have a lot of fat and thick fur on their bodies to protect themselves from the cold. Thick fats can withstand the cold and provide enough energy.

The size of the penguin is related to its living environment, because penguins live in very cold places, and the fat under their skin is very thick to withstand the cold of Antarctica.

The reason why penguins are chubby is because of the cold living environment, in order to keep the body temperature constant, so they need to store fat to maintain calories to maintain balance. It does have a certain relationship with the living environment.

Because the penguin is born with that kind of body, it will be fat, and its living environment is related, because the environment in which it lives is particularly cold, so this size is more conducive to survival.

It is because penguins adapt to life in the sea that they have evolved into a thick protective layer of fat under **. Yes, exactly, because penguins live in very cold conditions.

Because penguins live in Antarctica, where the weather is very cold. Yes, the size of the penguin has a lot to do with the living environment, and only such a size can withstand the cold of Antarctica.

Penguins' body size is inseparable from the living environment, because the environment is harsh and the food is very limited, so the food they eat in the stomach is converted into a thick fat accumulation to protect against the cold and hunger.

In this way, they can better survive in their place. Yes, the penguin is a very cute animal.

Because it lives in a relatively cold place, it needs a lot of fat to maintain its body temperature, which of course has a lot to do with it.

The smallest penguin in the world is called the Little Blue Penguin.

Little blue penguins are generally 43 cm tall and weigh about 1 kg, with males being slightly larger than females. The little blue penguin has blue feathers and is the only penguin with blue feathers, hence the name little blue penguin.

Extended information: Penguin is a generic term for all species of the class Ornithischia 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.

Due to the influence of the environment, in order to adapt to the harsh external conditions, the penguins have their own unique structure in their bodies. Penguins have three to four times more dense feathers than birds of the same size, and their role is mainly to regulate body temperature. Although penguins have the same legs as other flying birds, their bones are stiff and relatively short and flat.

This feature is combined with short wings like oars, which give penguins the feeling of flying underwater. The salt glands in the penguin's eyes excrete excess salt. The reason why they can see underwater and on the surface of the water is that their eyes have flat corneas, and the images they see can be processed by the brain to achieve the effect of long-sightedness.

Penguins are ancient animals, and they were probably the masters of Antarctica before it became what it is today. Ancient penguins have evolved themselves to adapt to the increasingly harsh weather in Antarctica. After countless centuries of reincarnation, their bodies have also become extremely self-defensive, and no matter how big a blizzard is, they are no match for them.

Penguins have evolved countless times, and their plumage has become overlapping, densely scaled. This special feather coat is not only difficult to penetrate by seawater, but the temperature is nearly 100 below zero, and it is not easy to break through its thermal insulation defense. Antarctica has a lot of land and a wide sea surface, and the abundant marine plankton is abundant food for penguins**.

Penguins are toothless, but they have barbs on their tongues and palates that help them adapt to eating fish and shrimp.

The penguin's body structure allows him to swim in the ocean, as well as find food in the water. Most penguins can dive deeper than other birds. In order to swim better, penguins have to give up certain abilities, such as not being able to fly like other birds.

Although penguins have wings, their wings are too small and their bodies are too heavy to fly.

Birds that can fly need large feathers to support them in the sky, but smaller feathers will be more suitable for penguin swimming. Penguins' bulky bodies make them more capable of swimming and diving than other lighter birds that can fly.

Large wings are very dexterous in water, and long feathers will bend and pull into the water, which will reduce the wing's ability to swim. The small wings are like a stiff oar to the penguin, and they are covered with only small feathers, which contribute to the penguin's ability to propel and swim in the water. Penguin feathers are small and dense, with more than 70 feathers per square inch.

These feathers are often covered in grease so that their feathers are waterproof. The penguin's wings move like an oar, and it depends on him for moving forward and backward and swimming in the water. Like paddles, penguins have stiff wings with large, flat bones that prevent their wings from bending.

The bones of birds that can fly are hollow and filled with air, which reduces the weight of the body and makes it easy for penguins to leave the ground. But penguins have strong bones, which makes them physically weighty and easier to swim or dive. And the muscles that make a penguin's wings swing are the largest in a penguin.

Birds with heavier gravity, such as ducks, can float on the water and can use flippers to water ski if they want to move forward. The heavier penguin can dive into the water or use its powerful wings to move forward.

The distances at which penguins swim are very staggering, and they often act in groups. And when swimming, they will bang! Jumping out of the breath and then jumping back into the water, the penguin gets the air it needs without slowing down.

This method is called dolphin pose, because dolphins often swim in this way.

In order to get back to shore, most of the penguins swim to the shore where they can walk, but the Adélie penguin has a peculiar way of rushing out of the water like a rocket and jumping back to shore. They shot straight at a distance of about two meters, which is equivalent to six meters for a human swimmer, because he is only seventy centimeters tall.

All animals, including penguins, need to drink water, but seawater is the only water they can get. They have special glands that separate the salt from the water they drink. The salt is separated in liquid form, flowing out of the grooves of the bird's beak and dripping from the tip.

The emperor penguin bai, is the largest individual species in the penguin family

Large up to 120 cm, weighing up to 50 kg version, the only one in.

In Antarctica, female penguins lay one egg at a time, and male penguins hatch eggs, and the eggshell thickness of emperor penguin eggs can reach millimeters, which is as much as five times the thickness of ordinary eggshells.
