Authorities in Hong Kong intercepted some questionable cargo three years ago — a rather large shipment of shark fins that had originated in Panama. Shark fins are a hot commodity among some Asian communities for their use in soup, and most species are legally consumed in Hong Kong, but certain species are banned from international trade due to their extinction risk. And wouldn't you know it: this confiscated shipment contained nearly a ton of illegal hammerhead fins.

These related species — which, along with chimaeras, are known collectively as chondrichthyans — include some of the most threatened marine fishes in the world. Sharks and rays face a variety of threats depending on where they live and swim, but the biggest risk comes from overfishing, which takes a noticeable toll on these slow-growing, slow-to-reproduce animals. As a result, nearly 1 in 4 species of chondricthyan fishes is estimated to be, or assessed as, threatened, according to the IUCN Red List.
