Dune Scorpion
Smeringurus mesaensis
The Smeringurus mesaensis, known as the 'Dune Scorpion'. Once classified as Paruroctonus, it is a small-medium sized North American scorpion (2-2.7 inches). Perfectly adapted to life in the sandy dunes of the Sonoran Desert, it is distinguished by its pale color and the incredible disproportion of the hands (swollen and bulbous claws contrasting with filiform fingers). It is an exclusively nocturnal, fast and venomous hunter (but not lethal, wasp-like pain). Unlike the Hadrurus (which digs in hard clay), the Smeringurus is a patroller of quicksands, holing up by day at modest depths. Requires desert terrariums with very dry sand and torrid heat.

Soins, reproduction et cohabitation
Terrarium Setup: This recovery provides no enclosure or substrate prescription.
Lighting and Heating: This recovery sets no photoperiod or temperature target.
Humidity and Hydration: A peer-reviewed desiccation study measured sex-specific physiological responses in Smeringurus mesaensis. It found no significant sex effect on mass-loss rates, while female and male haemolymph-osmolality responses differed at the reported experimental mass-loss levels. These are stress-study observations, not a humidity, hydration, or dehydration protocol.
Feeding and Supplementation: This recovery sets no feeding or supplementation protocol.
Compatibility and Coexistence: This recovery makes no cohabitation recommendation.
Health and Common Diseases: This recovery provides no health, disease, toxicology, or treatment protocol.

Profil d'invertébré terrestre
- Régime alimentaire
- Carnivore
- It is an active hunter that aggressively pursues and consumes various insects, small wandering arachnids, and other small arthropods that it encounters on the loose sand surface at night.
- Taille adulte
- 8 cm
- Mode de vie/microhabitat
- Terrestrial
- It is a psammophilous (sand-loving) fossorial scorpion. It specifically prefers extremely loose sand habitats where it uses its specialized anatomy to dig shallow to medium-depth burrows for shelter.
- Cycle d'activité
- Nocturnal
- This scorpion is strictly nocturnal. It emerges exclusively at night to actively hunt on the surface of sand dunes, completely burying itself deeply during the day to avoid the intense sun.
- Sociabilité
- Solitary
- They are solitary creatures. They are highly aggressive towards one another and possess strong cannibalistic tendencies. They must be housed individually to ensure their safety and survival.
- Reproduction
- Oviparous
- They are viviparous. Mating typically occurs directly on the surface of the loose sand. The female subsequently gives birth to live scorplings that ride on her back.
- Venimeux
- Yes
- Tolérance aux manipulations
- With caution
- Handling is highly not recommended. They are very fast-moving, highly defensive, and prone to stinging repeatedly if they feel cornered. Use long tongs for any required maintenance.
- Brumation
- Non requise
- It naturally experiences cooler winters in the American Southwest. While providing a slight winter cooling period is considered natural, it is not strictly required for their survival in captivity.
- Mue
- Regular
- It molts safely within its sandy burrow. It absolutely requires stable sand, often achieved by slightly moistening the lower substrate layers, to completely prevent fatal cave-ins during molting.
