Background and Research Aims: The global wildlife trade is a major driver of biodiversity loss, yet invertebrates remain largely overlooked in conservation policy and monitoring. Scorpions are ecologically important tropical arthropods, and Brazil harbors one of the world’s richest and most endemic scorpion faunas. Despite national legislation prohibiting the collection and commercialization of native wildlife, the extent of international online trade in Brazilian scorpions remains undocumented. We aimed to identify Brazilian species involved in the exotic pet trade using publicly accessible online data and to evaluate associated conservation and biosecurity concerns. Methods: We conducted systematic searches of public social media platforms and online marketplaces between January 2020 and December 2024 using Portuguese and English keywords related to scorpion trade. Posts explicitly indicating possession or sale were recorded, including species identity, country, year, and price when available. Results: We compiled 69 records involving nine species across five genera. Most posts originated outside Brazil, particularly in Europe and North America. Medically significant species, including Tityus serrulatus, Tityus stigmurus, and Atreus obscurus, were repeatedly detected. Records spanned more than a decade, indicating persistent international circulation, with only 26% of records including a price, and given prices ranging between US$12 and US$200. Conclusion: Brazilian scorpions are recurrently present in international online trade, representing an overlooked pathway for the circulation of tropical wildlife. Implications for Conservation: Digital trade exposes enforcement gaps and may contribute to unregulated extraction, biosecurity risks, and neglected pressures on tropical invertebrate biodiversity. Integrating invertebrates into wildlife trade monitoring is urgently needed.
