The genus recently carved out for the Chinese golden scorpion, and the strangest market backdrop in the order: the flagship species is farmed by the ton in China for food and traditional medicine while being studied intensively for venom peptides.
The venom is genuinely painful and clinically documented without reaching the Androctonus tier: respect, sealed housing, forceps. Hardy, arid, and cold-tolerant to a degree tropical-calibrated keepers underuse.
Hobby supply is a rounding error beside the farmed volume, so scarcity here is paperwork rather than biology. Both genus names, old Mesobuthus and new, live in the listings for the same animals, and the cross-search is the practical content of the label.
