Giant Madagascar Scorpion (Grosphus grandidieri)
Teruelius grandidieri
The Grosphus grandidieri, the 'Giant Madagascar Scorpion'. It is the most imposing representative of the genus Grosphus, exclusive (endemic) to Madagascar, capable of reaching 3.5-3.9 inches. Like all Buthids, it has a filiform silhouette, but is distinguished by its reddish-brown color with pale legs, and a venom that, although not lethal, causes acute pain. Inhabitant of the dry Malagasy forests, it is a terrestrial opportunist that takes refuge under roots or debris. Fast and active at night, it requires a dry-desert terrarium, sand and a rigorous African heat, proving to be a precious collector's item for breeders of hot (venomous) species thanks to its tolerance to gregariousness.

Description de l'espèce
Geographic Origin and Habitat: The published treatment lists material from Toliara Province in southwestern Madagascar, including a riparian-valley locality. It does not establish the full range.
Taxonomy and Genetics: The treatment uses Teruelius grandidieri (Kraepelin, 1901) comb. n.
Behaviour and Habits: No species-specific behaviour is measured.
Morphology and Sexual Dimorphism: The treatment records both male and female material, but this recovery does not extract a diagnosis or a captive identification rule.
Soins, reproduction et cohabitation
Terrarium Setup: A taxonomic treatment records one Teruelius grandidieri male in Antevankira forest near the Antsakabe River, in a riparian valley and a rotten tree trunk. This is a documented collection record, not an enclosure or substrate prescription.
Lighting and Heating: This recovery sets no photoperiod or temperature target.
Humidity and Hydration: This recovery sets no humidity or watering target.
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, or treatment protocol.

Profil d'invertébré terrestre
- Régime alimentaire
- Carnivore
- It is a voracious, aggressive apex predator of its micro-habitat. It eagerly hunts and consumes large crickets, massive roaches, and any other appropriately sized invertebrates it can overpower.
- Taille adulte
- 10 cm
- Mode de vie/microhabitat
- Terrestrial
- It leads a highly terrestrial and extensively fossorial lifestyle. It strongly prefers dry, sandy scrubland environments in Madagascar, where it functions as an incredibly powerful and efficient burrow digger.
- Cycle d'activité
- Nocturnal
- It is strictly nocturnal. To completely avoid the harsh heat, it retreats into deep underground burrows during the entire day, emerging onto the surface solely at night to hunt.
- Sociabilité
- Gregarious
- It is a fiercely solitary and highly cannibalistic species. Individuals are fiercely territorial over their burrows and must be housed strictly individually to completely prevent them from killing one another.
- Reproduction
- Viviparous
- Like other scorpions, it is viviparous. The female gives birth to live scorplings, which she vigorously guards and carries on her large back until they complete their first molt.
- Venimeux
- Yes
- Tolérance aux manipulations
- With caution
- Handling must be entirely avoided. It is a highly aggressive, deeply defensive scorpion with massive, powerful claws and a painful sting. Use long, heavy-duty tongs for all necessary interactions.
- Brumation
- Non requise
- As an endemic species of Madagascar's dry regions, it strictly requires consistently warm, high temperatures year-round. It absolutely does not undergo brumation and should never experience cold conditions.
- Mue
- Regular
- Molting occurs exclusively deep within the absolute privacy of its burrow. It requires deep, secure substrate to prevent collapses, and must be left entirely undisturbed throughout the lengthy process.
