Abstract

The deep-sea anglerfishes of the suborder Ceratioidei (Lophiiformes) are represented by about 170 valid species with some of the most extraordinary morphological and reproductive adaptations among vertebrates, including extreme sexual dimorphism and male parasitism. Here we report on the diversity and distribution of rare ceratioids collected during the ABRACOS (Acoustics along the BRAzilian COaSt) expeditions off northeastern Brazil and the Fernando de Noronha Ridge (Rocas Atoll, Fernando de Noronha Archipelago, and associated seamounts). Chaenophryne ramifera, Oneirodes anisacanthus, O. carlsbergi, Gigantactis watermani, and unidentified specimens of Caulophryne, Dolopichthys, and Rhynchactis are recorded for the first time in the Brazilian Exclusive Economic Zone. Ceratias uranoscopus, Melanocetus johnsonii, and Chaenophryne draco have their distributions extended in Brazilian waters. Caulophryne, O. anisacanthus, and G. watermani are also recorded for the first time in the western South Atlantic. The specimen of G. watermani reported here represents the third known specimen of the species, and variations of its escal anatomy in relation to the holotype are described. Based on specimens examined and a review of records in the literature, 20 species of the Ceratioidei, in addition to unidentified species of Caulophryne, Dolopichthys, and Rhynchactis, are confirmed in the Brazilian Exclusive Economic Zone.

No presente estudo reportamos sobre a diversidade e distribui&ccedil;&atilde;o de esp&eacute;cies raras de Ceratioidei coletadas durante as expedi&ccedil;&otilde;es ABRACOS (Acoustics along the BRAzilian COaSt) realizadas ao largo do nordeste do Brasil e na Cadeia de Fernando de Noronha (Atol das Rocas, Arquip&eacute;lago de Fernando de Noronha e montes submarinos associados). Chaenophryne ramifera, Oneirodes anisacanthus, O. carlsbergi, Gigantactis watermani e esp&eacute;cimes n&atilde;o identificados de Caulophryne, Dolopichthys e Rhynchactis s&atilde;o registrados pela primeira vez na Zona Econ&ocirc;mica Exclusiva brasileira. Ceratias uranoscopus, Melanocetus johnsonii e Chaenophryne draco tiveram suas distribui&ccedil;&otilde;es estendidas em &aacute;guas brasileiras. Caulophryne, O. anisacanthus e G. watermani tamb&eacute;m s&atilde;o registrados pela primeira vez no Atl&acirc;ntico Sul ocidental. O esp&eacute;cime de G. watermani reportado aqui representa o terceiro esp&eacute;cime conhecido da esp&eacute;cie, e varia&ccedil;&otilde;es anat&ocirc;micas de sua esca em rela&ccedil;&atilde;o &agrave; do hol&oacute;tipo s&atilde;o descritas. Com base nos esp&eacute;cimes examinados e na revis&atilde;o de registros na literatura, 20 esp&eacute;cies de Ceratioidei, al&eacute;m de esp&eacute;cies n&atilde;o identificadas de Caulophryne, Dolopichthys, and Rhynchactis, s&atilde;o confirmadas na Zona Econ&ocirc;mica Exclusiva brasileira.</p>
