In Hong Kong’s dried seafood stalls, shark fins no longer dominate. But rhino ray fins, which are rare, valuable, and from species now on the brink, still fetch fortunes.

Did you know? Sharks have some of the most diverse life histories. Even within shark species, life history traits vary dramatically! Some, like the Spiny Dogfish, can take up to 36 years to mature, while fast-growing species like the Australian Sharpnose Shark only take a year.
