Is walrus ivory and elephant ivory legally treated the same?
No. Even so, Elephants are not the ONLY endangered species.
Ton of info online if you care. We had enough of it I HAD to care, because even "Grandfathered" goods are subject to limitations just to legally cross a US State line or change hands amongst family members or within an Estate.
Experts, and even amateurs who have the need, can tell them apart from the far more common material sold to naive tourists (and my G'Dad and 2 Uncles in the Merchant Marine, or Dad in the souks of Bahrain whilst building Dhahran Airfield's new runways for B-36 use) AS "ivory".
As with MOST Tourists thinking they have a rare shot at valuable treasure- never stopping to wonder why a small hole-in-the wall stall always HAS "goods of great value" still to-hand as hundreds of customers a week pass through?
They mostly got f**ked!
Even fully synthetic Ivory is one of the OLDEST of all manmade synthetics that is any good at its job!
Much of it when "natural" is actually carved from the teeth of ignorant Middle Eastern CAMELS... who were worked hard, held in high regard, valued immensely.. and died of natural causes.
No "poaching" was involved until it came time to eat them.
Tough country. Tough crowd. Tough meat. Too severe to waste anything .. before it was discovered folks would actually pay more than two US dollars a barrel for ARAMCO's light, sweet, Arabian crude oil!
Folks adapt.
