Caraboctonus keyserlingi is a large, impressive scorpion native to the arid deserts and rocky valleys of northern Chile and southern Peru. It is the only species in its genus, making it taxonomically unique and instantly recognisable. Adults are robust and long‑bodied, with powerful pedipalps and a sandy, earth‑toned coloration that blends seamlessly with the desert terrain. Despite their size and imposing appearance, they are generally calm, slow‑moving animals that rely on retreat rather than aggression.
 
In the wild, this species shelters beneath stones, inside deep rock fissures, and in crevices where humidity remains slightly higher than the surrounding desert air. These microhabitats buffer them from the extreme daytime heat and allow them to maintain moisture balance in an otherwise harsh environment. They are nocturnal hunters, emerging at night to take small invertebrates and returning to their shelters before sunrise.
 
In captivity, C. keyserlingi thrives in dry, well‑ventilated enclosures with deep substrate, rocky hides, and a warm gradient. They are hardy, long‑lived, and display fascinating natural behaviours when provided with a structured, desert‑style setup. Their combination of size, uniqueness, and manageable temperament makes them a standout species for keepers who appreciate desert scorpions with real presence.
