Keep in mind that all the article really tells you is that customs intercepted a shipment of corals because they believe it contained endangered species and/or corals taken from protected areas.
If this is true, it is ashame, and gives out hobby a black eye.
By the same token, customs may be wrong. Many corals look alike, and identification can be difficult. The shipper and wholesaler deserve their day in court.
I seem to recall cases of US customs stopping clams from entering the USA, even though they were captive raised, and not endangered. Like corals, clams can be very difficult to identify if you don't know what to look for.
