Abstract
As a consequence of the severe drought in the Amazon region, there has been a decrease in the volume of water in the river basins and a loss of river flow in the northern region of Brazil. As a result of this factor, there has been a greater presence of marine waters entering continental regions, which is favoring the spread of the rainbow shrimp Mierspenaeopsis sculptilis (Heller, 1880), which is an exotic species to Brazil, but its presence is being expanded to estuarine waters in the municipalities of Colares, Vigia, São Caetano de Odivelas and Curuçá, all located in northeastern Pará. In these regions, its presence has been detected since September 2024, but the official records of the species are being made in this study. The presence of M. sculptilis in Brazilian waters may be linked to transportation by ballast water, in addition to its expansion in estuarine and marine waters in Brazil associated with climate change events. This study warns of the presence and high dissemination of the species in the northern region, and reinforces the need for mitigating measures to control the bioinvasion of M. sculptilis in Brazil.
