Those are some beautiful belts, whomewhat. RIDER: Fuscus is just a colour. It means 'brown' in Latin, although sometimes makers label their goods as Fuscus, so it ends up seeming like a species of its own. Caiman also just means alligator. There are only six crocodylia species that are suitable for making leather goods out of. This is determined entirely by CITES regulations. Basically, CITES App.II species can be imported/exported with the right permits, whereas App.I species are completely illegal. This info is available here, if anyone's interested:
http://www.cites.org/eng/app/appendices.shtml, and here's a summary: Alligator:
Mississippi - of course.
Caiman latirostris - Mostly harvested in Argentina. This type isn't tanned by any of our tanneries, but maybe it's out there.
Melanosuchus niger - Ecuadorian species, but regulation hasn't been established yet, so no one is tanning this one either. Crocodile:
Crocodylus acutus - Cuban crocodile. Haven't ever seen this one in high-quality tans, either.
Crocodylus niloticus - probably 3/4 of the time, anything crocodile is made out of this species. Harvested all over Africa. The best tanneries usually work with this one. Those erreghe belts are niloticus, without fault.
Crocodylus porosus - Harvested in Oceania. Also used by good tanneries. All other species are outlawed. The Alligator sinensis is among those - it's a Chinese species, and isn't harvested anywhere (legally) anymore. Same goes for Siamese crocodile.
