A Hong Kong-based non-profit organization called WildLifeRisk just exposed what it calls "the world's largest slaughtering facility for whale sharks," an endangered species. The facility, operating near the southeastern Chinese city of Wenzhou, processes an estimated 600 whale sharks each year, WildLifeRisk reports. The animals' parts and oils are used to make cosmetics, processed as traditional Chinese medicine, turned into leather and served in shark fin soup, according to the report.

The factory, which goes by the name "China Wenzhou Yueqing Marine Organisms Health Protection Foods Co Ltd," relies on middle men who source the 20 ton animals, which can fetch up to $30,000 each, says Business Insider.
