Yes, it's won! CITES Delegates voted overwhelmingly with 85% of the votes in favor of Mobula rays for their integration into Appendix II , which, let us remember, will make it possible to ban the international trade in Mobula rays. Admittedly, the vote must be confirmed in a few days during a final plenary session, but the chances are very high for adoption given the votes obtained.
