Evolutionary theory says that in the process of biological evolution, efforts are made to strengthen useful functions and weaken useless functions.
There is basically no light in the deep sea, so the biological eyes are basically completely degraded. It is useless to shock and warn people with bright colors and courtship, which is tantamount to walking in the night, so it gradually degenerates and tends to be consistent with the environmental color. So dark tones are popular in the deep sea.
The deep-sea area is vast and the environment is mixed, which is beneficial to biodiversity. Small-scale hybridization, large-scale isolation, the evolution of each organism is only suitable for a specific environment, even the same kind of organisms will show a variety of shapes.
"Why are deep-sea fish ugly?
1, the deep sea pressure is very high, and it grows like this to adjust the compressive effect of the body.
2, there is no light in the deep sea, so bright colors are useful, or dark colors are safer.
3. I think the more reliable answer should be evolution: that is to say, fish in the deep sea evolve slowly. Compared with shallow fish, there is more information about contact, especially with humans, so it has evolved rapidly, and the excellent side of protein has all evolved! However, deep-sea fish have little contact information and slow evolution, and the protein representation is in the primary or intermediate stage. So he looks a little ugly.

I heard that longevity fish is ugly. Why is it called longevity fish? Is it different from ordinary deep-sea fish?
Antarctic deep-sea longevity fish is a rare treasure from Antarctic deep-sea waters. It lives in the deep-sea low-temperature waters of 300 meters-1800 meters, feeds on polar krill, is natural and wild, has no pollution, and grows very slowly. The older the fish, the richer its nutritional value and the higher its price. The longest-lived fish lives to 170 years, which is the longest-lived fish in the world. All the long-lived fish caught by our vast fleet have an average life span of 150 years with a specification of more than 3 kg.
Although it is ugly, it has extremely high nutritional value.
Yu Changshou fish grows below 300 meters in the deep sea, so the brain death of Changshou fish will be caused by pressure after it is caught. In order to maintain the original freshness of longevity fish, our company immediately adopted the quick freezing technology after catching longevity fish, and quickly frozen it at the temperature of MINUS 60.
The fish skin is orange yellow, the meat color is super white, and the taste is delicate and elastic.

Fish head is rich in brain gold, which can activate brain cells, promote brain development for children, delay brain aging for the elderly and prevent Alzheimer's disease. Skull soup can nourish liver and kidney and prolong life.
