“…The fauna of the coastal and reef environments of the region is also poorly documented (Eskinazi & Lima, 1968, Collette & Rutzler 1977, Rocha & Rosa, 2001, Espírito-Santo & Isaac 2005, Moura et al, 2016, Marceniuk et al, 2017. However, several advances have been achieved in recent years, mainly through inventories conducted by the Research and Conservation National Center of Northern Marine Biodiversity, ICMBio/CEPNOR (Marceniuk et al, 2019), with important advances being made in the accumulation of specimens that confirm the presence of endemic species in the region (Caires et al, 2019), as well as records (Rotundo et al, 2019).…”

The North Coast of Brazil is a biogeographical area of the Exclusive Economic Zone of Brazil that share environmental features with region under influence of the Plume of the rio Amazon and Orinoco. Despite the relevance of the region’s fish fauna, in biogeo-graphic, ecologic, and commercial terms, this area is poorly known. This study presents the most complete and updated list of the bony fish fauna from the North Coast of Brazil, aiming to minimize our knowledge gap on such region's biodiversity. The main sources of infor-mation were records from zoological collections, inventories obtained during the surveys of the Research and Conservation National Center of Northern Marine Biodiversity and collec-tions from the authors. A total of 787 species of the Teleostei were recorded off the North Coast of Brazil and adjacent waters, representing 156 families and 45 orders. Most (531) of these species are coastal, 256 inhabit deeper water, and 31 pelagic (oceanic) species are com-mon to both the internal and external continental shelf, of which 54 represent new records. Given the progressive intensification of fisheries and increasing incentives for the exploita-tion of the local gas and oil reserves, a more adequate inventory of the marine fish fauna of the North Coast of Brazil is fundamentally important for the management of the region’s aquatic biodiversity.

Otolith shape analysis supports three cryptic species in the Stellifer punctatissimus complex (Acanthuriformes: Sciaenidae)

Sciaenidae species (croakers and drums) are known for specializations in their sensory apparatus, such as otoliths and lateral line. Within this family, some Stelliferinae members remain taxonomically unresolved due to their cryptic aspects and low phenotypic disparities. Stellifer punctatissimus comprises a species complex putatively formed by three species on morphological grounds, but molecular data have indicated only two evolutionary lineages. Herein, we tested the hypothesis that this complex is composed of Stellifer gomezi (GM), S. menezesi (MN), and S. punctatissimus (PC), using the otolith shape and morphology to differentiate them. Seventy-seven sagittal otoliths (GM = 30, MN = 30, PC = 17) were photographed to outline the otolith contour by Elliptical Fourier descriptors. Ten otoliths for each group were used to detect shape variation in the sulcus acusticus through semilandmarks. Differences in otolith shape contour were recorded among the species by PERMANOVA (Pseudo-F = 4.02, df = 2, p < 0.001) and corroborated by the Linear Discriminant Analysis, which demonstrated three partially segregated groups with satisfactory re-classification rates. A larger sulcus acusticus (GM and MN), rounded projection (PC), and distinct rectangularity pattern were also recorded. Our results support the morphological hypothesis and thus contribute to narrowing the taxonomic gaps in Sciaenidae.
