Antarctic krill is eaten a lot every year, is it really impossible to finish it? Krill: Probably Not Extinct

Krill have strong reproductive ability

There is a type of shrimp that is swallowed 300 million tons every year, but even so, they are still not worried about extinction. What is the source of this type of shrimp?

First of all, let us focus our attention on the Antarctic, which is one of the coldest regions in the world. The lowest temperature can reach -70 ℃, which is basically dripping into ice.

The strongest super thunderstorm can even reach above level 12. Such an extreme geographical environment is of course incompatible with people's survival. Therefore, it has become a natural paradise for animals.

There are many animals that live in Antarctica, and the shrimp that you will introduce in detail today is one of them. It is called Antarctic krill. Although Antarctic krill can be found all over the world, their key planting areas are located in In Antarctica, the population of Antarctic krill is also divided according to its biological distribution and type.

Antarctic krill can be found in a wide range. Their shadows can be seen from 500 meters to 1000 meters of seabed. Adult Antarctic krill are about 6 cm in length and about 2 weights each. The source of their ingredients So the zooplankton in the deep sea

The body structure of Antarctic krill is different. In their body, a fluorescent chemical substance also grows and develops. Many animals can find the existence of Antarctic krill based on this fluorescent chemical substance.

They can be described as microorganisms at the bottom of the food web, and are used as foraging targets by many marine animals. Little penguins, large turtles, and even huge dolphins will all capture Antarctic krill.

In particular, the giant fin whale in the dolphin can swallow 40,000 krill in one bite, and need to eat 6 tons of krill every day. It is their key source of food.

Not only fin whales, but many marine animals need to rely on krill for food. They are indispensable to the Antarctic ecological chain and have made lingering contributions to maintaining biological diversity.

Until modern times, people have also discovered the existence of Antarctic krill. Krill contains a variety of proteins and unsaturated fats. Their bodies also contain calcium hydrogen phosphate, which is a chemical substance with nutrients and excellent health care effects.

Therefore, many shrimp fishing boats rushed to the Antarctic to salvage krill. From the 1970s to today, about 300 million tons of krill are swallowed every year.

People's crazy salvage, coupled with the capture of marine animals, such a huge amount of use, is everyone not worried about the extinction of krill? In fact, the total number of Antarctic krill has not decreased significantly. In other words, krill is not at risk of extinction. Why is this?

Strong reproductive capacity of krill

Every year from November to December is the breeding season of Antarctic krill. As oviparous animals, their characteristic is "capable of being pregnant". During the breeding season, Antarctic krill will spawn 3 to 5 times. Egg production can reach 6,000 to 10,000

The survival rate of krill larvae is extremely high. After leaving the pregnant mother, it will sink to the bottom of the sea, and it will gradually move to the sea level after the larvae are hatched, which can reduce the risk of being caught. Capture, they also have brothers and sisters who can stand out from the encirclement and carry out the burden of reproduction again

Not only are they more abundant, but the krill are also very easy to grow and live. Their food sources are relatively simple, mainly dominated by algae plants in the deep sea. In the deep sea, the ingredients of algae plants are relatively abundant. The resources provide them with excellent living conditions, so the krill can grow and maintain such a huge population

The number of previous species has already laid a solid foundation for krill. Even if the other party can eat it again, relying on its own strong breeding ability, krill can still go against the sky.

Due to its own characteristics, krill is also called a bug in the deep sea. Many biologists feel that krill may become a key ingredient for people in the future. What do you think about this matter? Warmly welcome comments on the message board
