The pronunciation of Chinese horseshoe crab is zhōng huá hòu. Its body length can reach 60 centimeters and its weight is 3-5 kilograms. It is a very ancient marine arthropod with a shell and a sword-shaped tail. It lives on the seabed and can be used as medicine. It is also called Oriental horseshoe crab and horseshoe crab.

The Chinese horseshoe crab is a rare marine creature and is known as a "marine living fossil." Due to the impact of human activities, such as habitat destruction, overfishing and environmental pollution, the number of Chinese horseshoe crabs has been greatly reduced, and it is listed as a nationally protected wild animal.
