The genus Rhonciscus Jordan & Evermann, 1896 (Haemulidae) was recently revalidated, and it brought together four species allocated along with Pomadasys Lacepède, 1802, two from the Western Atlantic and two from the Eastern Pacific. However, the status of some of the species in the western South Atlantic was still doubtful. This study aims to review...
The genus Neoconger (family Moringuidae) is reviewed and our knowledge of it brought up to date. Six species are recognized, based on genetic and morphological information. Neoconger mucronatus Girard, 1858 occurs in the western Gulf of Mexico. Neoconger torrei (Howell Rivero, 1932) occurs in the Caribbean and along the coast of the Guianas. Neocon...
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classification. In this context, the B Brazilian meg...
The Brazilian North Coast (BNC) encompasses the intersection of multiple oceanographic features such as strong currents, a large continental shelf under the influence of the Amazon River freshwater and sediment outflow, extensive muddy and sand bottom, as well as a mesophotic reef system. As a result, the BNC hosts a diverse fish fauna, consisting...
Trypauchen vagina (Bloch & Schneider, 1801) is a goby that lives burrowed into
the substrata feeding on small invertebrates. It is native to the Indo-pacific region, ranging from Kuwait to China. Recently, this fish has been reported outside
the original range of distribution, being found in the Mediterranean Sea, and
more recently in the northeast...
This study integrates morphological and molecular data to redefine the taxonomic limits of Ophidion holbrookii, as well as its geographic ranges, with the description of a new species from the eastern and southeastern coast of Brazil, South America. Ophidion zavalai n. sp. is described based on variations related to ontogeny and sexual development...
The piramutaba, Brachyplatystoma vaillantii is a freshwater catfish that is the most abundant fishery resource in the Amazon estuary. Piramutaba trawling is done on industrial fishing scale and is characterized by the presence of many freshwater and marine bycatch species, with and without commercial value. Here we describe the bycatch of the indus...
Microphilypnus and Leptophilypnion are miniaturized genera within the family Eleotridae. The evolutionary relationships among these taxa are still poorly understood, and molecular analyses are restricted to mitochondrial genes, which have not been conclusive. We compiled both mitochondrial and nuclear genes to study the phylogenetic position of Mic...
The burrowing goby Trypauchen vagina has been reported from Brazil for the first time. This goby occurs naturally in the Indo‐Pacific region, where it is typically found burrowed in the bottom substrata of marine or brackish waters. Given its rapid development, extended longevity and multiple spawning cycles, the species is represented by large pop...
Citizen science is an excellent tool in studies of the spatial distribution of non‐native species. In Brazil, Opsanus beta has recently been introduced. Studies indicate the occurrence of this species in five estuaries off the Brazilian coast (Guanabara Bay, Sepetiba Bay, Santos Bay, Paranaguá Estuarine Complex and Guaratuba Bay). The present study...

The deep sea is the largest and one of the most extreme environments on Earth. It is estimated that 10–15% of all fish species are dwelling in the deep sea, most of which have unique morphological and physiological adaptations. Biological expeditions to sample the deep ocean off Brazil started with the British HMS Challenger Expedition (1872–1876),...
Data on the deep sea fishes found off the northern Brazilian coast are restricted to the results of the surveys of the RV Oregon, a research vessel of the North American National Marine Fisheries Service, and the REVIZEE Program. The REVIZEE Score-Norte Program focused on commercial fish species and natural resources with potential for exploitation...
The genus Menticirrhus is widely distributed in the Neotropical region, where its species are common and abundant in shallow coastal waters and estuaries. The diversity, biogeography, and evolutionary relationships of the Menticirrhus species are still poorly known, due primarily to the difficulty of differentiating the species, given the broad sim...

The taxonomic status of three species of eels described from leptocephali larvae in 1960, is revised and elucidated: Leptocephalus anaelisae Tommasi, 1960, a member of Moringuidae, is confirmed as a junior synonym of Neoconger mucronatus Girard, 1858; Leptocephalus juliae Tommasi, 1960, a Muraenidae, is confirmed as a junior synonym of Uropterygius...
Scorpaena inermis is recorded for the third time in the southwestern Atlantic. The known previous records of the species from Brazilian coast was collected Alagoas and Rio Grande do Norte states, prior of which the species was supposed to occur only in the northwestern Atlantic, from Georgia, USA, to Suriname and French Guiana. Here we report on tw...
Background:
Nature is perceived in a variety of forms, and the perception of nature can also be expressed in different ways. Local art may represent the perception of nature by humans. It can embody perception, imagination and wisdom. Local art, in particular, reflects how people interact with nature. For example, when studying the representation...
