Why penguins are the best divers among birds

In order to be able to reproduce in the cold winter of Antarctica, emperor penguins have developed stronger cold protection and diving skills, and the deepest diving record can even reach 565 meters, making them well-deserved seabird diving champions.

Most seabirds do not feed on the surface of the sea, and they have to dive to the bottom to catch food. The diving depths of various seabirds vary, some are three or four meters long, and some are more than 10 meters or even deeper. So, which seabird is a true diving champion?

According to records, cormorants can dive up to 37 meters, white-headed divers can dive up to 60 meters, Antarctic penguins can dive 80 meters, sea ducks can dive to a depth of 180 meters, and emperor penguins can dive to a depth of 500 meters, which can be called the crown of seabird diving.

The emperor penguin, as its name suggests, is the largest of the penguin family, with an average height of over 90 centimeters, the largest reaching 120 centimeters and weighing up to 50 kilograms. They generally dive to the bottom of the sea to 150,500 metres to feed, feeding mainly on crustaceans, but occasionally catching small fish and squid.

Emperor penguins are covered with scale-like feathers, which are thick and thick. For swimming, their wings have been transformed into well-developed flippers that can be used as paddling tools. Their hind limbs are short and powerful, webbed between their toes, and they are extremely fast in water.

The penguin's hard and smooth "feather cape", thick fat layer, and unique body metabolism are all strong guarantees for it to become the most capable diving champion of marine birds.

As global temperatures continue to rise, so does the temperature of the sea, causing a drastic reduction in food** for emperor penguins, and their habitat is deteriorating. The latest research points to the melting of Antarctic ice as a result of climate change. It is estimated that in another 100 years or so, the Antarctic emperor penguin population will be less than half of what it is today.

Scientists have called for emperor penguins to be classified as "endangered" to reduce the impact of climate change on them.

Penguins are typical seabirds and are also typical land animals. But on land, it is like a Western gentleman in a tuxedo, walking, swaying, encountering danger, falling and climbing, embarrassed. Although it can't fly, in the water, the penguin's short wings become a pair of powerful "paddles", and its swimming skills are super competitors among birds.

Penguins can swim at speeds of up to 25-30 kilometers per hour. You can travel 160 kilometers in one day. It mainly feeds on krill, squid, and small fish.

Many waterfowl swim by paddling through the water with their webbed feet, and although the penguin's feet are also webbed, they are only used as rudders to control the direction, and the power to move forward is all by the pair of oar-like wings, which flutter their wings in the water, that is, the penguin swims in the water with its fin-like forelimbs, which is exactly the same as the movement of birds flying in the air.

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.

No other terrestrial animal can dive so deep and dive for so long. Therefore, penguins are the well-deserved diving champions among birds.

Penguins are birds. It belongs to the marine bird animal and is a typical seabird.

Penguins, like ostriches, are a group of flightless birds. According to fossil data, the earliest penguins were able to fly, and it was not until 650,000 years ago that their wings slowly evolved into flippers that could swim in the water, and became the penguins we see today.

There are many species of birds, which can be described as widespread and ecologically diverse, and now birds are mainly divided into three general orders:

1. Flat-chested general order, including a class of birds that are good at walking but cannot fly, such as ostriches.

2. Penguins, including a class of birds that are good at swimming and diving but cannot fly, such as penguins.

3. Protruding chest, including birds with developed wings and able to fly, the vast majority of birds belong to this order.

Bilingual example sentence: penguins are actually birdsPenguins are actually birds.

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 found in the Southern Hemisphere. It lives mainly in the southern hemisphere and belongs to the order of Penguins, the penguin family.

Penguins are birds, it is an animal of the genus Penguin, and the animals in the class are birds, although penguins do not have the ability to fly, but its physiological characteristics are exactly the same as birds, such as penguins have feathers on the body surface, will use oviparous reproduction, etc., penguins are relatively old and flight ability degraded birds.

1. It's a bird

Penguins are birds, it is a relatively old and vestigial bird, the penguin's body is covered with thick feathers, and there is air between the feathers, which is convenient for penguins to keep warm, so that they can live in a cold environment, and there are 18 species of penguins, the common ones are emperor penguins, yellow-eyed penguins, yellow-eyed penguins, etc.

2. Emperor penguins

The emperor penguin, also known as the emperor penguin, is the largest species of penguins, with a maximum height of 120 centimeters, and the emperor penguin has orange feathers under its neck, it breeds on the icebergs of Antarctica, and the female emperor penguin lays only one egg at a time, while the male emperor penguin is responsible for incubating the eggs.

3. Yellow-browed penguins

With an average body length of 55 centimeters, an orange-yellow beak and pink feet, the yellow-browed penguin lives mainly in the ocean between Australia and Antarctica, where they gather to raise their offspring.

4. Yellow-eyed penguins

The yellow-eyed penguin is 56-78 cm tall, its pupils are pale yellow, and the male yellow-eyed penguin has a relatively bright yellow feather on the head, while the female yellow-eyed penguin has a gray head and no yellow feathers, the yellow-eyed penguin mainly inhabits around the coastline of New Zealand, and it is a terrestrial animal.

Penguins are birds, which belong to the subclass of birds - Penguin Order - Penguin family in the biological classification, and are the oldest migratory bird creatures; Birds are divided into six categories: migratory birds, wading birds, climbing birds, land birds, birds of prey, and songbirds, among which domestic birds are more common larks, thrushes, indigos, embroidered eyes, red birds, shellfish, pips, sunspots, starlings, canaries, budgies, etc.

Penguins are birds. There are 18 species of penguins in the world, most of which are distributed and live in the Southern Hemisphere. Penguins are homeothermic animals, and there are only two types of homeothermic animals:

Birds and mammals. Penguins are characterized by their inability to fly, and they are able to live and breed in cold climates. The penguin is one of the oldest migratory birds, having lived here before Antarctica became a glacier.

Penguins are known as the "boat of the ocean", and there are 18 species of penguins in the world, most of which are found in the southern hemisphere. It lives mainly in the Southern Hemisphere and belongs to the order Penguin, the penguin family.

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 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.
