Whales are large mammals that live in the ocean, what are the types of whales?

Whales - I believe that most people have learned about them when they first came into contact with marine life, they are big, they eat a lot, and I still remember what my elementary school teacher mentioned to us, a whale can have a square table in its mouth, and four people sit in it to play cards to describe the whale's hugeness.

Whales are large mammals that live in the ocean, and some whales also live in rivers, and the whales that people generally know live in the ocean. There are two main groups of whales. One is baleen whales, which are suborders of baleen whales, which are toothless and bearded.

These whales are generally large. The other type is the toothed whale, that is, the toothed whale suborder, this kind of whale has teeth, they are different in size, basically not very large, like a fish, so people call them "whales". There are many types of whales.

1.Killer whales

It is the most ferocious of the cetaceans. The body size is not very large. They live in groups and cooperate with other whales when hunting. It mainly preys on penguins, seals, and some other cetaceans.

2.Blue whale

It is the largest whale in size. The largest is more than 30 meters long and weighs hundreds of tons. Despite its huge size, it has a gentle temperament and concealed whereabouts, like a "sweetheart" you can never figure out.

Blue whales mainly prey on crustaceans such as krill and small fish.

3.Beluga

Beluga whale is a relatively small whale that weighs about a ton. We can see them inside the aquarium. Beluga whales generally live in estuaries or coastal areas with good water quality. They have protruding foreheads and look a little cute.

4.Narwhal

It is not large, about 5 meters long. It lives mainly in cold seas, roughly near the Arctic Circle. They mainly prey on fish such as cod. They tend to be on a diet in the summer and eat like crazy in the winter.

5.Sperm whales

Sperm whales are the largest toothed whales. The longest body length can reach 18 meters. They are very powerful dives and are currently the longest and deepest mammals. Sperm whales secrete a kind of "ambergris" in their intestines, which is very effective in medicine.

6.Humpback whales

Humpback whales are one of the ugliest whales. Don't look at it ugly, it's still very gentle. Humpback whales, mainly prey on some krill and small fish. When it comes to humpback whales, they hate the Japanese even more, and they resolutely continue to hunt humpback whales despite the opposition and condemnation of the people of the world.

There are two main types of whales, one is baleen whales, which have no teeth; One type is toothed whales, which have sharp teeth. There are also sub-categories, including blue whales, humpback whales, killer whales, beluga whales, etc. There are about 6 genera and 11 species of baleen cetaceans in the world, including three families: the right whale family, the gray whale family and the fin whale family.

There are still many types of whales, including killer whales, blue whales, humpback whales, and toothed whales, all of which are particularly large and have particularly sharp teeth.

There are two main types of whales, one is baleen whales and the other is toothed whales, which have very sharp suppression.

It is a mammal. Whale. Although it has the word fish, it is not a fish, but a mammal that lives in water, and has the same physiological characteristics as land mammals, such as breathing with lungs, constant body temperature, viviparity, etc., and has some special physiological structures that have evolved to adapt to the aquatic environment.

Whales and land mammals.

The same is viviparous, and the calf is born directly from the belly of the mother whale.

Notes:Whales have a thick layer of fat under their skin, which is called whale oil, which keeps the whale warm and can also store energy for emergencies.

Because whales have many special structures in their bodies, they can hold their breath and slow down their heartbeat for a long time, so when they sink to the bottom of the sea, it will always take a long time before they resurface. In addition to having a structure to store oxygen, when a certain part of the body needs a large amount of blood**, there will also be a special function in the body to concentrate**.

Whales are mammals. Whales can be collectively referred to as cetaceans or cetaceans, which are a taxa under the class Mammals, and have been confirmed by relevant studies that cetaceans evolved from terrestrial artodactyls about 50 million years ago, and have mammalian characteristics.

Whales have mammalian characteristics, such as reproduction, whales only produce one cub per litter, and at the same time have a long growth period, because the reproductive efficiency is not high, at present, about a quarter of the species of whales are endangered under human hunting.

Whales are currently the largest group of creatures in the world, and the largest of the cetaceans is about 239 tons, which is about 50 times the weight of the average elephant.

Whales are mammals that need to breathe, so why do they still live in the sea?

Because he is a special mammal, and he is a creature of the ocean, a lot of people like this creature because he needs to live in water, so he is a mammal, but he needs water to survive.

Because of the changes in the earth's environment, whales came to the ocean and began a long evolution, and their snouts gradually evolved to the top of their heads. When they are in the ocean, their nostrils (stomata) are closed, and when they come to the surface, they open their stomata to breathe.

It is because the origin of all living things evolved from the ocean, and whales once wanted to live on land, but due to the influence of natural predators and the environment, they returned to the ocean.

In the process of sleeping, they can't wake up for a while, and go to the surface of the sea for a while to breathe freely. Scientists have found that whales did not live in the ocean at the beginning, about 50 million years ago, because of changes in the earth's environment, whales came to the ocean to start a long evolution, at that time their noses have evolved to the top of their heads, when they are in the ocean, their nostrils (stomata) are closed, only when they surface the sea, will open the stomata and inject fresh air into themselves.

It's because the environment in the sea is very conducive to its growth and reproduction, so it will be in the sea.

In fact, all the creatures on land originated from the sea, but in later evolution, only whales remained in the sea.

It is because of its body structure that allows it to survive well in the sea, and it is very easy to die if it is on land.

Because whales are too large and have not evolved limbs suitable for life on land, this means that land is not suitable for whales, and they can only live in the sea.

Because it can live very freely in the ocean, it may not be able to play on land.

Like all animals, whales breathe with lungs and are warm-blooded animals with their young fed by suckling and a little hair. The forelimbs of the whale form fins, the hind limbs are completely vestigial, and the tail becomes a caudal fin with nostrils in the upper part of the head. Of particular note is the blue whale.

It is the largest living animal in the world, with a body length of up to 30 meters and a weight of 180 tons. So it's mammals.

Because whales breathe with their lungs, they are also viviparous.

For example: bats. Cat. Horse.

Sheep. Dog. Pigs and celery and so on are dairy catchers!
