UPS Finally Banned Shark Fins. What Now? - Motherboard UPS was shipping the fins of thresher shark and smooth hammerhead, both listed as “vulnerable,” and the blue shark, listed as “near threatened” by the International Union for Conservation of Nature. Other documents show that the company was also shipping oceanic white tips, a protected species for which trade is tightly controlled. When pressed on the issue and presented with a petition with over 177,000 signatures, a spokesperson for UPS told Motherboard that the company “ships shark fins that are legal to ship.” But on Monday night, UPS finally caved. The company tweeted that it was joining a growing list of others that are refusing to ship shark fins.
