A DECADE OF PROGRESS FOR SHARKS This past year, by any measure, was groundbreaking for shark conservation: a total of 27 countries of the European Union banned shark finning. There were other hopeful signs for sharks. In March 2013, five species of sharks—scalloped hammerhead (Sphyrna lewini), smooth hammerhead (S. zygaena), great hammerhead (S. mokarran), oceanic whitetip (Carcharhinus longimanus) and porbeagle (Lamna nasus)— were added to CITES Appendix II. This listing should reduce cross-border trade in the fins of these species and alleviate fishing pressure.
