Atlas of marine bony fish otoliths of Southeastern-Southern Brazil Part VIII: Siluriformes (Ariidae) and Pleuronectiformes (Achiridae, Paralichthyidae, Cynoglossidae)

Abstract To complement the series of manuscripts published as "Atlas of Teleostei Otoliths of the Southeastern-Southern Brazil", in this volume we present results for species of Siluriformes (two species) and Pleuronectiformes (thirteen species) orders. Considering that the sagittae of Siluriformes are very small we analyzed the left lapillus. Due to the asymmetry of the Pleuronectiformes otoliths, were analysed both left and right structures, being the circumsulcal depression the most important feature to diagnose these species.
