I think the implications of being placed on the endangered species list under the Endangered Species Act (ESA) would be a complete ban on commercial import/export of those corals in the US. Currently, stony corals are in Appendix II which means the species are not necessarily threatened with extinction globally and trade is allowed but regulated (meaning permits are required). If those proposed corals are listed as endangered under the ESA, then I think those specified corals will be relisted into Appendix I of CITES which essentially places a ban on commercial import/export of those corals and that would affect all countries that follow CITES as well. That is my interpretation. But I don't know. These things are confusing.

"If listed, the corals would be banned from collection in U.S. waters, banned from import into the United States; interstate shipment would become illegal. Captive propagation would require a federal permit, and corals could only be bought and sold within states. “Effectively, this would end the international trade in stony corals to the United States,” Meyers said in an exclusive interview with CORAL Magazine."
