This fish with a simple English name is Rory—— in Chinese-a tall golden-eyed snapper.
This kind of fish belongs to golden-eyed snapper and looks very threatening. Their big teeth also gave it a name "Fang", and its terrible appearance gave it such a terrible English name "Piranha".
Fangs inhabit particularly deep places in the ocean. Although their most common habitat is 500-2000 meters, their horrible home is in the middle of an abyss as deep as 5000 meters, where the water pressure is terrible and the temperature is close to freezing point. There is a shortage of food here, so these fish eat everything they see. Most of their food may come from the upper ocean. Although this kind of fish is not afraid of cold, it is distributed in the depths of tropical and temperate oceans because more food falls from them. Adult fish with fangs look very different from young fish. The skull of young fish is long and light gray, with a big head and a big mouth, and the color ranges from dark brown to black. Young fish don't start to look like adults until they grow to 8 cm. Young fish eat crustaceans, and adult fish eat fish.
