How do whales chew their food?

Whales are divided into toothed whales and baleen whales. Toothed whales are not as big as baleen whales. But agile.

What baleen whales eat is called filtering type. Toothed whales are called carnivores when they eat. There are three kinds of toothed whales, those that eat squid, those that eat fish and those that eat meat.

Let's start with baleen whales. Baleen whales have teeth in the fetal period. But when they grew up, they all disappeared It can be seen that it originally originated from a species with teeth. Whale is not an inorganic salt such as calcium like teeth, but something made of chitin like comb teeth. What is chitin? It is a kind of thing connected by acetylglucosamine, which is the hard shell of shrimp, crab and insect.

The baleen whale is very big. On the one hand, those krill, small fish and so on, although small, are numerous. The more you eat, the greater your appetite and the greater your physique. Besides. As a kind of herbivorous animal, fin whales have weak attack power, so they must increase their physique to protect themselves. In fact, eating krill at the bottom of the sea is really similar to eating grass.

The baleen whale does have a small throat. Because the individual of food is very small, there is no need to have a wide throat. A little bigger fish can't swallow. It can be seen that people can't swallow. But it is not easy to swim out. I think I must be promoted. After all, it's too stressful to swallow saliva. That is, the moment you speak, you will have a chance.

A whale has 200-300 pieces of this stuff in its mouth. You can imagine how big your mouth is. The tentacles of the blue whale are 90- 1 10 cm long and 50-60 cm wide, sometimes ivory white, sometimes excrement yellow, sometimes hell black ... high and grounded. The blue whale has a black beard. Whale whiskers can be used as handicrafts. And you can be my sister's skirt. Very good. I don't know how many times better than plastic with plasticizer. So whales were arrested and killed ... and of course oil.

There are two other ways for baleen whales to eat. One is called swallowing filter type. Swallow water and food into your mouth, then close your mouth and squeeze out the water with tongue pressure. Swallow it. That's what blue whales do.

The other is skimming, that is, swimming around in the water with an open mouth, revealing a small head. When the food in your mouth is almost the same, leave your mouth out of the water and let the water flow downwards by gravity. Swallow it. Humpback whales were swept by. By contrast, humpback whales are really smart. Let's talk about it below.

Whales are hot and big, and their heads are of course gray. The skull of a sperm whale is only one third as big as its whole body. However, it is hard to say whether IQ can catch up with human beings. At least whales have not developed our civilization. Anyway, remember, a big brain may not necessarily have a high IQ. An elephant's head is bigger than a man's. Moreover, the whale's brain is actually not big, mainly thick bones and fat. At least, whales can learn other people's hunting skills. Learn while watching.

Humpback whales, for example, used to confuse krill by spraying bubbles under them and gathering them together for hunting. And humpback whales swim in circles, which can form bubble net. Krill's IQ is relatively low, so it can't swim out without finding a gap, so it can only wait for humpback whales to gobble up. However, there is less oxygen in the lungs and the time of persistence is short. Krill groups are usually close to the water surface. A humpback whale is smarter. He has innovated the method of making bubbles. He uses his tail and fins to make bubbles to gather krill together, so that he can eat more krill. Then all the other humpback whales knew ... and there was no patent or anything.

There is also a story about humpback whales. It is said that sometimes humpback whales go to the bottom of the sea to catch small fish without fish. Humpback whales cannot swallow big fish. Okay ... they like to eat things from the bottom of the sea. Similar to eels, this fish will always hide in the sand at the bottom of the sea. Humpback whales will make a "tick" sound, especially when hunting together. They will keep ticking, and then the sand will vibrate under the influence of vibration, and the small fish in the sand will jump out. This is really the call of hell.

Do you want to hear another story about humpback whales ... humpback whales swim in the water when they eat. Don't shoot bubbles, don't tick, just sprint predation. When the mouth is opened more than 90 degrees, it is more than 4.5 meters wide, sideways, sideways and crooked. Anyway, you will go to the krill. In order to open my mouth, all the wrinkles on my body are stretched out. Well, wrinkles ...

Like the little eel whale, it belongs to the baleen whale and eats krill. But it's not just krill that eats Yujin. Is there a more special hunting technique than humpback whales? They like to eat at 5- 10 in the morning and 14- 18 in the evening. I don't eat at noon I don't eat in the afternoon. I don't eat at night. Although there are only two meals a day, it seems that there is nothing unhealthy.

Speaking of baleen whales, let's talk about toothed whales. Sperm whales come first. After all, it is the largest toothed whale. Sperm whales basically don't eat fish, but mainly eat various squid and octopus. For example, what squid, claw squid, octopus ... The so-called octopus is octopus. You see, sperm whales eat grilled octopus every day. Shameless.

Squid is preyed.

These squid also roll up and down in the seawater, and the deepest point can reach 1000 meters. Sperm whales are even tougher, and 2500 can dive. Sperm whales' biggest food is king squid. This is a big, big sea monster squid. The king squid is very big, generally 20 meters long and 80 meters long. It is simply a sea monster. King squid doesn't eat sperm whales, and sperm whales eat king squid. These two animals are just fighting. The king squid is also fierce. Look, this is the remains of the king squid.

Sometimes sperm whales also eat fish, when there are no squid. Like cod. Why do you have to eat squid? Because the sperm whale is a toothed whale, its upper jaw has no teeth, or even if it has teeth, it has no function. It's small, just for display. Only the lower jaw has really sharp teeth, 20 cm long and 10 cm in diameter. And the teeth in the lower jaw are all the same. You can't bite, you can only chew and swallow. So squid is the best food with thin shell and soft meat.

Whales and squid are coevolutionary. Just like leopards and antelopes run faster with evolution. The ability of squid to escape by inkjet. Color change, jet propulsion, big eyes, sperm whale's nose, sonar, body structure, gastrointestinal tract and so on all evolved together. It's also fun. Is there wood?

In addition to sperm whales eating squid, there are sperm whales, swordfish whales and so on.

Black whales prey on great white sharks.

Killer whales are the only animals that eat meat. Penguins, seals and dolphins all eat. Even blue whales dare to move in groups.

All kinds of whales eat 280 million to 500 million tons of marine animals a year, which is equivalent to 3-6 times the annual marine catch of human beings. It is delicious, isn't it? Moreover, whales will destroy fishing nets, interfere with operations, disperse fish schools, and even run into fishing nets to eat. You really know where to choose. IQ is high enough. The Japanese go whaling for this reason. But most scientists in the world disagree with the Japanese. Whales mainly eat krill and fish that humans don't eat. For example, no one can really eat or catch the jade fish at the bottom of the sea. Therefore, it is naive to think that whales have more fish without them. Can't you see there are not many deer without wolves? Predators are useful. Humans are not predators. Because humans take things in order. Better than god.

Whales are the top predators in the ocean. Its status is self-evident. But humans have killed too many whales. Especially unintentional killing, such as fishing, such as making a loud noise. Whales are extremely sensitive to sound, and there is no sound on the bottom of the sea. Humans make too much noise. When the noise is too loud, whales feel that there is no love in life, so they rush to the beach and run aground and die. Anatomy found that most stranded whales have inner ear bleeding, brain, throat and hearing system damage. It can be seen that the grounding is mostly man-made. Lying in the trough, the noise is too dry. Ah, ah, ah ... I'd better die. He is dead.
