When it comes to Japan, everyone will think of local food. In recent years, the publicity of Japanese cuisine is also very strong. In the past, people's diet knowledge was for satiety, but now it is for delicacy and nutrition. Now freshwater fish can't meet people's needs, and gradually turn their attention to marine fish, and Japan is very close to the sea, so seafood is also very famous.

There is a kind of fish with a particularly long mouth in the local area, so the locals named it open-mouthed fish. Octopus is black all over and is very common in the local area. As long as you touch its mouth with your hand, it will stick out its mouth. Whenever they need to hunt in the sea, they will lengthen their mouths by about 10 cm, which will cause negative pressure inside and outside the body to suck food into their mouths. The food they often catch is generally small fish and shrimp.

This kind of fish has a considerable feature that it will change sex. In fact, all fish are born female. When they grow up, the biggest fish in the group will change their sex to male, so that they can occupy all the females and mate to give birth to small fish. But if there are other females in the population, they will become males when they grow up, and the winner can mate with other females.

Although this kind of fish looks ordinary, it is deeply loved by local people. The method is also very simple. Just clean the fish scales and internal organs, then boil them with hot water and rinse them with cold water, then cut off the fish fillets and dip them in the sauce. Because Japanese prefer sashimi, many people think it is delicious. To be honest, I can't accept eating fish raw. If I want to eat, I can try Japan.
