Body shape variations help to diminish taxonomy uncertainty in juvenile swimming crab Callinectes Stimpson, 1860

In 2019 an oil spill spread over more than 4000 km of the Brazilian coastline.Monitoring programs that allow for the evaluation of potential impacts on communities and ecosystems and their recovery through time are needed and rely on baseline information previous to the oil spill. Here we compiled qualitative and quantitative data available from 8 studies on fi sh and benthic species from different habitats of Rio Grande do Norte (RN) from 2007 to 2018. We assessed the number of species from different locations and compiled information on conservation status and human use. We mapped the study areas and habitats and overlapped them with those affected by the oil spill. The RN state has a high diversity of fi sh (175 species) and benthic species (285 species), of which more than half of fi sh (52%) and 2% of benthic species are threatened and 72,8% of fi sh and 7,9% of benthic species are of commercial interest. Information of most habitats is still poorly known (i.e.majority ofthe available data are from unique and punctual sampling), which may weaken future evaluations of the real impact of the oil spill. Nonetheless, it is possible to design reliable monitoring based on our dataset, persistent contamination and future loss of diversity.
