W. auteur aut IRD text journalArticle eng text/pdf reformatted digital access The deep-sea anglerfishes ofthe 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 waterinani, and unidentified specimens of Caulophryne, Dolopichthys, and Rhynchaais are recorded for the first time in the Brazilian Exdusive Economic Zone. Ceratias uranoscopus, Melanocetus johnsonii, and Chaenophryne draco have their distributions extended in Brazilian waters. Caulophryne, O. anisacanthus, and G. waterrnani are also recorded for the first time in the western South Atlantic. The specimen of G. waterrnani 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 Exdusive Economic Zone. specialized Distribution Fernando de Noronha Archipelago Rocas Atoll Seamounts Taxonomy BRESIL FERNANDO DE NORONHA ARCHIPEL ROCAS ATOLL 034 020 19 2 200151 [28 p.] 2021 1679-6225 https://www.documentation.ird.fr/hor/fdi:010082183 10.1590/1982-0224-2020-0151 1679-6225 [F B010082183] https://www.documentation.ird.fr/hor/fdi:010082183 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2021-08/010082183.pdf IRD - Base Horizon / Pleins textes 2021-08-31 2025-02-24 fdi:010082183 fre
