The distribution of Squilla brasiliensis Caiman, 1917 (Crustacea Stomatopoda) is by the first time discussed in the continental plataform in the region of Rio Grande do Sul State, in relationship with depth, temperature and salinity. Apparently the distribution of that species is more related to salinity than to depth and temperature, and specially to the water mass of Subtropical origin. The largest densities were found between 84 and 128 m depth.
