The late John Andrew Musick (1941–2021), widely known as Jack Musick, was a prominent marine scientist of the Virginia Institute of Marine Science who worked chiefly on sea turtles (Chelonioidea) and elasmobranchs. Here, we aim to disclose Jack’s impact on the development of elasmobranch research in Brazil by reconstructing Jack’s academic genealog...
Background
The paper presents an extensive dataset of the shallow reef fish communities and habitat characteristics in the Fernando de Noronha Archipelago (Southwest Atlantic). The data were collected from August to October 2006 in the Fernando de Noronha main island. To evaluate the shallow reef fish communities, 165 visual censuses were performed...
Freshwater or euryhaline sharks and rays are usually a forgotten
component of shark, ray, and chimera biodiversity, mainly
because the vast majority of these species are associated with
marine ecosystems. Freshwater rays are cartilaginous fish species
that have adapted and developed the ability to live and complete
their entire life cycles in fresh...
The family Potamotrygonidae is part of the Neotropical ichthyofauna and has the largest diversity of freshwater elasmobranchs in the world. The neurocranium in Potamotrygonidae is an elongated and dorsoventrally flattened structure that articulates anterolaterally with the anterior portion of the propterygium, posteriorly with the sinarcual, and po...

The Great Hammerhead Shark, Sphyrna mokarran, is critically endangered around the world. The overwhelming majority of their records are of animals killed, quartered or captured by fishermen, which limit our understanding on its biology and conservation. For the first time, we report on the S. mokarran occurrence in the State of Paraíba, Northeaster...
The Paraiba River estuary is the largest and most important estuary of Paraiba state, northeastern Brazil. It is under intense environmental degradation by the surrounding human population, and possibly several fish species are at risk in this habitat. Scientific sampling of the ichthyofauna started in the late 1970’s and proceeded until recently....
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 thr...
The dog snapper, Lutjanus jocu, is a commercially exploited fish throughout the Brazilian Province (BP) and has been facing overexploitation. However, there are no systematized data on the species to date, which hinders management strategies for mitigating this scenario. In this review, we gathered the existing literature information on L. jocu alo...
Many reef fishes move between different coastal systems throughout their ontogeny, but these movements are complex and often not understood. In this study, we examined how the dog snapper (Lutjanus jocu) uses marine and estuarine habitats across the Abrolhos Bank shelf (eastern Brazil) through the analysis of elemental signatures in otoliths. Speci...
Fisheries can act as top predators and affect marine biodiversity and ecosystem functioning via their target species. We studied a coastal food web in the Pacific Ocean that is modular and encompasses species and small-and large-scale fisheries. Small-scale fisheries (SSF), two hammerhead sharks, one stingray, and one flatfish species are netwo...
Chocó-Darien is an important biogeographic realm, as it is a terrestrial biodiversity hotspot and the southern limit of the Caribbean reefs. 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 geo...
We report a choking event involving a Bocon toadfish Amphichthys cryptocentrus and a Madamango sea catfish Cathorops spixii. 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 undetermin...
The genus Paratrygon, currently recognized as the sole monotypic genus of the family Potamotrygonidae, has a considerably greater diversity than previously indicated, including molecular studies, which supported P. aiereba (hitherto the only recognized species in the genus) as a possible species complex. Here we describe two new species of the genu...
Despite a vast number of studies about shallow reef fish assemblages, and an increasing amount of studies about mesophotic ones, there are very few cross-shelf assessments including both, shallow and mesophotic depths. Herein, we analyze changes in reef fish assemblages in a cross-shelf euphotic-mesophotic (19–72.6 m) gradient in tropical SW Atlant...
Centropomus Lacépède, 1802 comprises 13 species of the fishes popularly knows as snooks, distributed in both Atlantic and Pacific coasts of America. Despite several studies on the group, conflicting taxonomic classifications still exist, including overlapping diagnostic characters, rendering species diagnoses extremely difficult. Herein, we review...
Sciaenidae (croakers) is one of the most speciose fish families in the marine Neotropical realm, with its diversification in this region closely linked to the uplift of the Isthmus of Panama. Within the Sciaenidae, members of the Stelliferinae remain taxonomically unresolved due to their cryptic aspects and low phenotypic disparities, hampering the...
