True, but Cassis cornuta and Turbo marmoratus (in addition to the CITES species
of all Tridacna [and really Hippopos?] and Charonia tritonis) are forbidden to
be exported by the PHILIPPINE government, independent of international
regulations.  They want to sell them to you, of course, but at the same time
everybody is aware of the ban, strange situation.
