The horseshoe crab is an arthropod, also known as the horseshoe crab. It generally lives in shallow marine areas and feeds on small marine animals. Whenever horseshoe crab breeding season arrives, male and female horseshoe crabs go to the beach together to lay their eggs. This creature is very ancient and can be described as a true “living fossil” of Earth. Relevant fossil data shows that horseshoe crabs appeared on earth at least 450 million years ago (Ordovician).

A substance contained in the blood of horseshoe crabs is extracted and made into a reagent, which can easily, efficiently and accurately test drugs and medical supplies.
