Genus Smeringurus

The big pale dune scorpions of the Mojave and Sonoran sand seas, among the fastest scorpions anyone keeps, and sand specialists in the strict sense.

Mild-venomed, with speed rather than sting as the maintenance consideration. Genuine deep loose sand is the entire husbandry, and the rock-dwelling member of the genus swaps that for crevice stacking. Sedentary, hardy, seasonal.

Southwestern collection supplies the trade in season and vanishes otherwise, nobody breeds them because nobody needs to, and the listing-level blur with Paruroctonus runs in both directions. The permanent US-native structure holds: collected, cyclical, priced by abundance, and never anything else.
