CITES Appendix II listing for Silky Sharks
Cities Appendix II listing
A listing on CITES Appendix II means that the trade of that animal must be controlled in order to avoid endangerment and extinction. If the person/company/country etc cannot show proof of sustainability, then the animal cannot be traded. This, in effect, leads to their protection, as it is nearly impossible to prove sustainable trade of these animals.
