The East African giants split out of Pandinus, heavy-clawed, mild-venomed, and carrying the split's paperwork as their defining trade fact.
The keeping is the emperor-adjacent package entire: burrowing, humidity-wanting, communal with reservations, UV-fluorescent, forgiving. The thick-pincer-thin-tail rule reads correctly across the genus.
The CITES listings written against the old genus map unevenly onto the new names, so international purchases deserve a documents check that domestic ones do not. Within the market, the emperor's name recognition does the sorting: same shelf appeal under a less famous word, steady East African supply, and listing depth that tracks the famous relative rather than these animals.
