Usually what we say about Piranha refers to carnivorous food. Sexual red-bellied sawfish. This kind of piranha is often so cruel that it can even be eaten by humans. Their expressions will also vary depending on how they rest.
The piranha has red eyes, an oval body, flat sides, and a rounded tail fin. The body is gray-green, the back is tea-green, and the abdomen is bright red. It has sharp teeth and a spiky lower jaw, and is famous for its fierceness. It is more difficult to distinguish between males and females. Generally, male fish have more beautiful faces and are generally smaller, while female fish are generally larger and lighter in face, and their abdomens are more stretched when they are sexually mature.
Mature piranha males and females have similar appearances, with bright green backs and bright red abdomens, and patterns on their sides. Have highly developed hearing. The two jaws are short and powerful, and the lower jaw is overhanging. The teeth are triangular and sharp, and are connected to each other on the left and right. After biting the prey, it bites tightly and uses the twist of its body to tear off the meat. It can bite off 16 cubic centimeters of meat in one bite. The rotation of teeth allows them to continue to look for food, and strong teeth can cause serious bite injuries.
