Jayakar’s scorpion (Hottentotta jayakari) is a medium-sized, robust scorpion endemic to the arid and semi-desert regions of the Arabian Peninsula (including the UAE, Oman, and Saudi Arabia) and into southern Iran. Adults reach 60–80 mm in length, with a characteristic sandy-yellow to reddish carapace and darker metasomal (tail) segments. Nocturnal by habit, they shelter under rocks and in shallow burrows by day and emerge at night to hunt insects and other small invertebrates. Although its venom can cause significant pain and localized swelling, serious systemic effects are rare in healthy adults. Jayakar’s scorpion has not yet been formally assessed by the IUCN (“Not Evaluated”), but field observations indicate it is widespread and locally common throughout its range—making it an essential predator in desert food webs and a frequent encounter for herpers in the UAE.
