The blue whale is a giant of the seas

Absolutely not, the Japanese are.

(1) A large blue whale is simply a small mountain.

For example, the blue whale is tall and vivid, and it can reach a body length of more than 30 meters and weigh more than 170 tons, which is equivalent to the weight of 300 cattle.

Column numbers (for comparison) Specific and accurate descriptions (body length, weight) and highlight the weight of the blue whale.

3) Its mouth, in particular, can accommodate more than a dozen adults to sleep in it.

Compare the size of a blue whale's mouth with that of an adult).

1.The analogy shows that the blue whale is very large 2The column number shows that the blue whale is heavy 3For example, a blue whale has a large mouth.

Human beings should reflect on themselves, they should not become the public enemies of animals, and every life deserves to be treated kindly.

The blue whale is known as the overlord of the sea, does it really have no natural predators on the seabed? There are two creatures that it fears the most.

As one of the largest creatures in the ocean, whales still have enemies in the ocean, and if they encounter a swarm of sharks, they may be eaten.

In a general sense, the blue whale has no natural predators because of its huge size. There aren't too many creatures capable of attacking him. But killer whales attack the calves of blue whales, but they are not natural predators of blue whales.

There are no natural predators. However, some animals will sneak up on blue whale calves that have not yet grown, such as herds of killer whales to hunt them.

There are basically no natural predators, and the blue whale basically does not encounter animals that can pose a threat to it during its lifetime.

It must have natural predators, and there is a cycle in the way every species in nature survivesIf the animals in the highest places do not have food, there is no way to survive. But if anyone has no natural predators, it should be the blue whale. Blue whales are the most ferocious hunters in the ocean, and the blue whales must be a whole group.

For blue whales, we humans are their real predators！In the age of whale hunting, humans killed 90 percent of the blue whales on the planet. Scientists have also said that a hundred years ago, there were more than 300,000 blue whales on the earth, but after more than half a century of human hunting, there were less than 20,000 left.

Now that humans have completely stopped hunting blue whales, the number of blue whales is gradually rising, but it is still far less than the population before humans hunted blue whales, and blue whales are still an endangered species.

In addition, other human activities also seriously threaten the survival of many marine animals, including blue whales. Organic and chemical pollution of the ocean affects the reproductive and immune systems of blue whales and other marine mammals. Blue whales rely on hearing and echolocation to navigate.

Offshore oil and gas extraction, as well as noise pollution from human sonar systems and equipment, interfere with their navigation, causing them to swim too shallow and close to the coast, leaving them stranded ashore and eventually dying. Commercial fishing is doubly dangerous, overfishing reduces the food for blue whales, and the nets entangle the blue whales, causing them to suffocate to death because they cannot reach the surface to breathe.

Finally, I would like to say that the ocean is also a necessary condition for our survival, and if the marine environment is guaranteed, then our life will gradually improve. As young people, we can vigorously publicize and popularize the knowledge of marine environmental protection, and raise people's awareness of the importance of the ocean to us. It is necessary to vigorously promote the knowledge of conservation and environmental protection to family and children, as well as people in the vicinity, so that all animals and plants can live in harmony.

Killer whales, the natural predators of blue whales in the ocean, may be one of them. AlthoughAdult blue whales are many times larger than killer whales, but blue whales are a very big threat to juvenile blue whales. And apart from killer whales, I think humans are their biggest predators.

Some oceanographers have found killer whale attack scars on many blue whales, and these blue whales are all adults. Many people believe that these wounds were left by the attack of killer whales when they were minors. Because the adult blue whale is more than twice as big as the killer whale, both in terms of physique and combat effectiveness the killer whale has been beaten by the adult blue whale, and it can even be said that ifAfter the killer whale encounters an adult blue whale, the adult blue whale can stun the killer whale with a single tail.

But in the midst of wealth and danger, killer whales will still hunt blue whales, but they are all in the juvenile period. A newborn blue whale after encountering a killer whale. Killer whales will fight in groups, isolate the baby blue whale and the blue whale mother, and then round up the baby blue whale

And sub-adult blue whales can't escape the hunt of killer whales, and some people have even photographed thirty or forty killer whales besieging sub-adult blue whales. So killer whales actually pose a threat to blue whales, but they are all when they are minors.

And when the blue whale becomes an adult, their only natural enemy may be only us humans, such as Japan, every year under the banner of scientific research whaling ships wantonly kill all kinds of cetaceans, the blue whale is the first to bear the brunt, the sea water even because of their blood turned red, at this time, even as the overlord of the ocean blue whale is powerless to resist. And as people continue to explore the ocean, the noise of sonar systems and ship propellers has brought great challenges to the survival of blue whales, as we can often see blue whales stranded on the shore because they have lost their way. We can't stop the world of the jungle, but I don't think we, as humans, should stop hunting blue whales.

If it is a juvenile blue whale, dozens of killer whales besieging it should cause harm, but in fact, killer whales are not considered natural enemies, the biggest natural enemies of blue whales are still humans, whaling ships and other large ships and submarine ultrasound are much larger than the number of deaths caused by killer whales every year.

Blue whales are basically at the top of the food chain in the ocean, and if you want to talk about natural enemies, the killer whales of the ocean are likely to take the initiative to attack blue whales, especially for juvenile blue whale cubs, and then humans are the culprits who kill blue whales.

There are probably predators, but the number of blue whales is very small, and the number of human hunts is becoming less and less.

The blue whale is at the top of the food chain, and its biggest natural predator is humans, in addition to humans, killer whales.

There should still be natural predators, otherwise the blue whale can reproduce endlessly, which is not conducive to the survival of other creatures.

I think there should be natural predators, but there should be relatively few, because after all, the blue whale is so powerful.

I feel that it must have natural predators in the ocean, because the food chain is all living and fighting.

There are natural predators, but it is not known who they are. On earth, there are natural predators.

A: The body cavity of a blue whale is 36 times the weight of a hippopotamus

2) and tremor with 108 6 = 18

A: Blue whales weigh 18 times the weight of elephants

3) How many times does an elephant weigh more than a hippopotamus?

A: An elephant weighs twice as much as a hippopotamus

Water drop boat world animal marine mammal - whale its blue whale body is about a meter and weighs about a ton, which is similar to an elephant or a bull.

Who would have thought that Pang Whale, (competing) the ocean's excellent swimmer Jianhai Overlord Killer Whale every swim; The 100-ton sperm whale ocean diving champion has some other whale skills: it is forbidden to swim at full speed (i.e., both) and braking; It can not only be fast, but also have the potential to float quickly, and no ship can reach it.

The whale has a special body shape: the body shrinks rapidly, the tail forelimbs evolve, the flippers have degenerated, the whole body resembles (trees), and the body shape pulls water droplets, which can reduce water resistance and adapt to water.

Ship designers associate ship design from the shape of the whale body, the water droplets resemble whale-shaped ships (have been) to some vicious passenger ships, cargo ships, and water departments are now changed to whale-shaped supertanker models (imitation), whale body shape, speed up.

1 is just in case.

2 Expansion Decreased.

4. Immediately reach full speed swimming from stationary and can immediately "brake"; fast dive; Float quickly.

5 Ability Body shape.
