So, which species has the most valuable fin on the market? You may be surprised to know that's it's not actually a shark, but rather a type of ray called the wedgefish. Although they look like sharks, their gills are on the bottom of their body as opposed to the side, one of the distinguishing features between sharks and rays. Their tall dorsal fins and large tail fin have the best shape and texture for shark fin soup. All species of wedgefish are vulnerable to extinction due to targeted and incidental fisheries as well as habitat loss. . 📷: GlobalFinPrint Sampling: Mozambique / Australian Institute of Marine Science, marinemegafauna, fishecolab & vulcaninc . #Wedgefish #sharkfinsoup #fintrade #IUCNRedList #RayRevolution
