Why is the Arctic jellyfish so big? Is it the cause of the ocean???

The specific species are not clear, but it is certain that there is a tendency for the creatures of the Arctic and Antarctic to become gigantic, and there may be 4 reasons

1.The larger the volume, the smaller the surface area per unit weight, which is not conducive to heat dissipation and heat preservation. So the Siberian tiger is the largest tiger and the polar bear is the biggest.

Jellyfish are not cold-blooded animals, and do they have a heat preservation factor? The reason for warm-blooded animals is the main factor, but the impact of cold-blooded animals is much smaller, but cold-blooded animals still have some thermal insulation needs, such as the digestive organs are a little hotter to improve digestion efficiency.

2.Store energy. Large bodies bring more energy reserves, and when it is not easy to forage, large creatures form a selective advantage. It is not easy to forage in the Arctic and Antarctica, and the environment changes greatly in winter and summer, and the large size of the jellyfish naturally takes advantage of it.

3.Oxygen supply. Jellyfish don't have a heart, and the circulatory system relies on osmosis for breathing, which means that the larger it is, the more difficult it is for oxygen to penetrate it.

It's a biological knot, and it's because of this that insects can't grow bigger. The giant ant in the movie is impossible to appear, it is so big, the internal organs do not get oxygen, and it will die long ago, unless the film director arranges for the ant to evolve a heart. Water, on the other hand, is characterized by the fact that the lower the temperature, the more oxygen can be dissolved.

Compared to the tropics, the oxygen content of Antarctic and Antarctic waters is very high, which can support the huge body of jellyfish.

4.Low metabolism, older age. The reason for the low metabolism is that the aquatic animals of the Arctic and Antarctic are generally longer than their tropical counterparts, and the low temperature is not conducive to the spread of infectious diseases, and the probability of dying from the disease is also low.

Yes, in the vast ocean jellyfish can only grow, because the water-carrying marine life needs all the indicators that we can't artificially do, even the aquarium can't clone the great nature!

The tentacle length is 36 meters, which is longer than the blue whale.

The Arctic jellyfish is a super giant in the ocean, the body length of the Arctic jellyfish can reach more than 30 meters long, the average length of the tentacles is about 20-30 meters, the tentacles of the largest Arctic jellyfish found in the world have reached 36 meters, although the Arctic jellyfish is huge, but it also has natural enemies, and the leatherback turtle will also go to catch the Arctic jellyfish to become a "good meal". Walk.

Introduction to the Arctic jellyfish: The Arctic jellyfish is a lower coelenterate, which belongs to the phylum Coelenterates and the class Bowl Jellyfish in taxonomic terms. There are many species of jellyfish, about 250 species in the world, ranging in diameter from 10 cm to 100 cm, and are commonly found in the oceans everywhere.

The umbrella shape of the Arctic jellyfish will shine with colorful light, but the lifespan is generally only about one year, and the length of the tentacles of the Arctic jellyfish can reach about 20-30 meters, and there are stinging cells on the tentacles to secrete toxins. Arctic glow.

Is jellyfish the largest in the world? Generally speaking, the size of the stool and the jellyfish is not very large, only about 30 centimeters, among which the largest jellyfish is the Arctic jellyfish, the diameter of the giant umbrella of the Arctic jellyfish can reach up to 2 meters, and the tentacles reach 20-30 meters, in 1865, on the coast of Massachusetts, USA, there is a jellyfish washed ashore by the waves, its umbrella diameter is meters, the tentacles are 36 meters long, the tentacles of the jellyfish are pulled apart, from the tip of one tentacle to the tip of another tentacle, it is 74 meters long.
