A few days ago, a news story about "a woman buying a monster in the mouth of a fish that she bought home" caused a lot of commotion. Judging from the pictures, the monster is a little scary and disgusting. If you find this creature in the mouth of the fish, can you just throw the fish or take out the monster?
<h2>Monsters are nothing</h2>
The monster's Chinese are called the shrunken-headed fish lice, most of which are parasitic on marine fish, and a few are parasitic on freshwater fish. It has a very typical relationship with parasitic to symbiotic fish, and is the only organism currently found in the family Dipteridae that can replace the host's tongue.
Parasitism and symbiosis are very common in the biological world. Parasitism: Two organisms live together, one benefits and the other suffers, such as mites and humans, blood-sucking worms and people. Among them, the injured party is called the host, also called the host. Symbiosis: Two organisms live together and benefit from each other.
<h2>What to do if you find out</h2>
The head-shrinking fish lice are not distributed in China, and there is no data to show that the head-shrinking fish lice are harmful to the human body. Because of the symbiotic relationship, there is no other harm to fish, mainly feeding on the mucus secreted by fish. Therefore, when handling imported seafood fish, if you encounter a fish lice with a shrunken head, you can take it out and throw it away.
But we should remind everyone that although domestic fish are difficult to encounter the shrunken head fish lice, it will parasitize a creature of different genera from its same family, called the fish turtle. It generally parasitizes in the chest cavity of carp and crucian carp and does not convert to a symbiotic relationship, so parasitic fish usually grow slowly, thin and lose reproductive ability. However, it is not harmful to the human body, but is still a Chinese herbal medicine. Although it does not affect consumption, the nutritional value of the boarding fish is greatly reduced. Therefore, when buying fish, you must look at whether the fish body is complete, whether there are holes in the pectoral fin, and throw away all the internal organs when cleaning, and the fish is steamed and cooked before eating.
