While scorpion fauna of the Baja California Peninsula is well known for diversity, the biology of individual species has been less studied. The objective of the study was to assess abundance of scorpions of the coastal dunes at Laguna Manuela, Baja California, Mexico. In total, 182 scorpions were marked during 4 nights of sampling. Vejovoidus longiunguis (Williams, 1969), a purported dune specialist, was in extraordinarily large numbers relative to Centruroides exilicauda (Wood, 1863), a widespread habitat generalist species. The results contrasted with previous studies of V. longiunguis in different areas of its range.
