The Caribbean blue scorpions, formerly Rhopalurus, stridulating audibly and carrying one of the stranger fames in the hobby: venom marketed in folk cancer preparations, a use with deep cultural roots and no clinical support, which deserves stating exactly that plainly.
Moderate venom warranting respect without Tityus-class alarm, quick, crevice-and-scrub dwelling, sealed and forceps-kept.
Cuban export is nonexistent and Hispaniolan movement is thin, so island endemism plus the genus rename fragments a small supply across two names and several islands. The folklore keeps demand ahead of a production that cannot scale, and both genus words persist in listings for the same animals.
