After 450 Million Years, the Chinese Horseshoe Crab is now Endangered

October 5, 2019

China: The horseshoe crab has been around since before the dinosaurs. Over the past 30 years, numbers in China, home to one of four species of this “living fossil”, have plummeted. One of the main reasons is demand for the animal’s copper-based blood, which is used to make the most sensitive indicator of bacteria ever discovered. In March this year, the International Union for Conservation of Nature (IUCN) listed the Chinese horseshoe crab (also known as the tri-spine horseshoe) as endangered. But few people in China are aware of the plight of this 450-million-year- old creature, and experts are calling for stronger measures to protect it. download the pdf.
