However, to date there are no compiled data on the reef fish assemblage of this region. We provide an updated checklist of marine fishes from the Chocó-Darien reef system (Colombia), with comments on their geographic distribution and conservation status. Peer-reviewed studies, unpublished data and in situ visual censuses were surveyed to compose this checklist. A total of 212 reef fish species across 57 families were compiled, eight of which had no previously published records, one of which (Trachinotus falcatus) is recorded for the first time. The most speciose families were Labridae (n = 21), Gobiidae (n = 18) and Serranidae (n = 17). Fourteen threatened species were recorded, including one critically endangered (Epinephelus striatus) and two endangered (Balistes vetula and Scarus coelestinus). This study contributes to fill the knowledge gap...

Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data se...

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 ...

The sea catfish was lodged into the oral cavity of the toadfish and possibly caused the predator’s death by asphyxiation. This is the first record of a Bocon toadfish preying and choking on a sea catfish, but it is undeterminable whether the predation was accidental or purposeful.

Knowledge of phylogenetic relationships of this genus have been improved by shared advances of classical and genetic approaches. However, some of its species have yet to be compared regarding its genetic patterns. Morphological variations in body shape and color patterns during the course of ontogenetic development, in addition to recurring sex reversal in species of this genus, make its taxonomy challenging. In the Atlantic Ocean five species have been described: Bodianus scrofa and Bodianus speciosus (Eastern Atlantic), Bodianus rufus (Western Atlantic), Bodianus pulchellus (Western Atlantic and Eastern Atlantic Islands) and Bodianus insularis (Mid-Atlantic islands). The phylogenetic relationships of the last species could not be resolved using genetic analyses. With a very restrict geographic distribution, B. insularis deserves high attention regarding its taxon...

Its temporary drainages are receptors of the São Francisco interbasin water transfer project (SFR-IWT) in the Brazilian semiarid. We provide a comprehensive baseline of fish richness of the five SFR-IWT basins. Species richness, shared, endemic, threatened and non-native species were obtained using sampling, ichthyologic collections, literature and online repositories (306 localities). In total 121, species were recorded, 111 of them native, and 16 (14.41%) listed for all basins. Higher richness of native species (78, 70.27%) was recorded in the São Francisco lower-middle stretch (SFRE), including 23 endemic, 61 (54.95%) in MNCE basins (13 endemic), and 28 (25.23%) shared between both ecoregions. In the MNCE, 50 species were recorded in Jaguaribe (JAG), 39 in Piranhas-Açu, 36 in Paraíba do Norte, and 32 in Apodi-Mossoró (APO). The number of species shared between the SFRE and each ...

As presas foram identificados até o menor nível taxonômico possível e classificadas com o auxílio do Índice de Importância Relativa (IRI). Um total de 76 indivíduos foram analisados, com a predominância de jovens. Vinte e cinco estômagos estavam vazios, 14 contendo somente massa amorfa e o restante dos estômagos (37) tinha no mínimo uma presa em processo de digestão. O item predominante foi peixes teleósteos, presente em todos os estômagos com conteúdo (83,8%), seguidos de crustáceos (18,9%) e moluscos (13.5%), totalizando 11 grupos taxonômicos identificados: peixes (Clupeidae, Engraulidae, Holocentridae, Ophichtidae, Pomacentridae e Pleuronectoidei), crustáceos (Isopoda, Stomatopoda e Penaeidae) e moluscos (Octopodidae e Loliginidae). Não foram identificadas diferenças significativas nos itens alimentares entre machos e fêmeas ou entre jovens e adultos. O Índice...

Most lagoons included in the study were <2 km(2) , with a maximum of 3975 km(2) in surface area. Combined surface area of all lagoons included in the study was 5411 km(2) . Number of species varied locally from one to 76. A multiple regression revealed that latitude, attributes of morphometry and connectivity, and sampling effort explained a large amount of variability in species richness. Lagoon area was a good predictor of species richness except in low latitude ecoregions, where lagoons are typically small-sized and not affected by marine immigrants, and where non-native fish species accounted for a significant portion of species richness. Relationships between species and area in small-si...

Recreational divers found and photographed a bitten nurse shark carcass, just after sighting two tiger sharks near of the site. We estimated the sharks total lengths and discussed aspects of this feeding interaction using of images of forensic analysis. A straight cut on the nurse shark caudal fin, whose total lenght was estimated as 200 cm, suggest that it was caught by illegal fishing. A skin peeling process on the nurse shark fins indicates that the tiger sharks consumed it after its death, in a scavenging event. This is the first published report of a scavenging event involving the consumption ofan elasmobranch by tiger sharks, allowing a better comprehension of tiger sharks’ alimentary biology.

Despite several studies on the group, conflicting taxonomic classifications still exist, including overlapping diagnostic characters, rendering species diagnoses extremely difficult. Herein, we review the taxonomy of Centropomus to elucidate species identities, redefine their diagnoses and to assess interspecific relationships based on the examination of 376 specimens. The study included complementary approaches, as analyses of external morphologic characters, linear and geometric morphometrics, and molecular analyses. Forty-nine characters were used for external morphology, 17 discrete plus 32 linear measurements. Shape and size were analyzed through geometric morphometrics of 185 specimens in lateral view. Partial sequences of the gene cytochrome c oxidase I were obtained for 129 specimens representing 11 species. Based on the consist...

O objetivo do presente estudo foi analisar os aspectos etnoecológicos dos pescadores de "currais" em Cabedelo, litoral da Paraíba. A pesquisa foi desenvolvida com pescadores (n=7) através de excursões quinzenais, de acordo com a variação das marés nos cinco meses de sua despesca (Novembro, 2012 a Março de 2013) totalizando 21 coletas. Pescadores de diferentes modalidades de pesca também foram entrevistados (n=20) com objetivo de confirmar memes locais. Os métodos adotados foram a técnica "bola de neve" ("snow ball"), observação direta, com entrevistas informais e formulários semiestruturados além da utilização do índice de constância, do valor de uso, econômico e taxonomia folk. Na composição da ictiofauna foram registradas 25 espécies de peixes, distribuídas em 15 famílias. A distribuição espacial dos peixes pode ser ...

O objetivo do presente estudo foi caracterizar e descrever as formas de manejo destes “currais” pelos pescadores do litoral da Paraíba. Foram utilizadas entrevistas livres, “rapport”,“Snow ball” e formulário semiestruturado nas visitas mensais aos cinco “currais” entre os meses de novembro 2012 até março de 2013. Foi quantificada a produção dos currais e identificada as espécies mais capturadas. Os dados mostraram que estas armadilhas são constituídas por compartimentos e passam por fases em terra e mar até serem totalmente ativadas. O total da produção de peixes foi de 303 kg. As espécies predominantes foram: Mugil curema and Mugil liza, Trichiurus lepturus, Caranx hippos, Selene vomer, Selene setapinnis, Diapterus auratus e Diapterus rhombeus. Conclui-se que este tipo de pesca é utilizado há décadas no lito...

This report describes the seasonal occurrence of the Lineated Woodpecker (Dryocopus lineatus) in a small riparian fragment of Atlantic Forest, northeastern Brazil. A female was recorded by its visual and acoustical signals from September to October 2014. Similar occurrences were observed in the same months over three consecutive years. Two major hypotheses regarding the woodpecker seasonal occurrence are discussed here: i) the use of the riparian fragment for breeding, evidenced by tree-cavity nests; and ii) fleeing of the bird from its natal habitat due to fire in adjacent sugarcane fields, which commonly are burned in these two months. Such recurrent events suggest that D. lineatus uses the riparian fragment as refuge habitat, highlighting the importance of these environments for bird populations that inhabit fragmented landscapes of the Brazilian At...
