In coastal environments, ballast water and sediments, basement water and fouling on the hull and on other parts of ships are the main vectors of the biological invasions. The benthic fauna, with high diversity, is outstanding among the species being transported and, in Brazil there are relatively few studies of invasive species. In this study, a compilation of the records of exotic benthic organisms in Brazil was accomplished, with its origins and current distribution. It was listed a total of 41 species of several origins, mostly from Asia. The occurrences of exotic species have been recorded in 24 Brazilian states, especially at those with large ports. The species with larger distribution and records in Brazil were Melanoides tuberculatus, Corbicula fluminea, Litopenaeus vannamei and Charybdis hellerii. Keywords: Benthos; bioinvasion; occurrence; brazilian territory.
