Taeniasis is a parasitic disease that affects humans and fish. Once a person eats undercooked or raw fish with parasitic spargan parasites, the spargan parasites in them will become parasitic in the human intestines. It takes 5 to 6 weeks to develop into adult worms, causing human fish tapeworm disease.

Flounder is the epitome of this. In any environment, even if it is blind, its body color can become exactly the same as the environment.

When the body color is extremely bright and beautiful, it is usually very dangerous and unpalatable.

It is used to warn the enemy not to eat it, otherwise it will be thankless.

Protection:

Freshwater fish usually live in inland waters. However, in recent decades, economic development, population increase, environmental pollution, indiscriminate reclamation, indiscriminate construction, dam construction, and arbitrary Problems such as the introduction of non-native species and over-harvesting have caused irreparable damage to the natural habitats and water quality of freshwater fish, resulting in a significant decline in the species and numbers of aquatic animals.

About 1,800 species of freshwater fish are endangered, and some species have even become extinct. If a species becomes extinct, it will destroy the food chain and seriously affect the ecological balance.

Inbreeding will affect human offspring. This law also applies to fish. If fish are inbred, it will cause the fish to become smaller. This situation is common in fish farms.
