Shark bones are a part of deep-sea sharks. Since sharks became seafood, the style of shark bones has also been developed by people. Now people pay more attention to health preservation, not only to eat better, but also to be more nutritious and innovative, so there is shark bone.

Shark bone is a kind of seafood that has just entered the public's field of vision in modern times. The method of shark bone is relatively simple, and it is more suitable for eating as a side dish. It is also a good choice to crush shark bones and make them into meatballs, fry them with meat and cooked food, or add shark bones to soup when stewing fish and add some vinegar to soften them. Shark bones are softened and marinated, and eaten with white rice.

Sharks belong to cartilaginous fish, a subclass of vertebrates, and live in the ocean. A few species enter fresh water, which is a group of medium and large marine fish with fast swimming speed.

The endoskeleton of sharks is completely composed of cartilage, which is often calcified, but there is no real bone tissue. The exoskeleton is not developed or degenerated. The body is often covered with skin teeth (thin-walled scales), with various teeth and hard muscles, but the membranous bone never exists and the skull is seamless.

The upper forehead is composed of palatal cartilage and the lower forehead is composed of Mayer cartilage. The latest research shows that sharks contain many bioactive components, such as anticancer factors, squalene, mucopolysaccharide and so on. The medicinal use of sharks was first seen in Notes on Materia Medica. In China, shark cartilage extract and shark liver oil have long been used to treat cancer and other diseases.
