Five species of marine fishes are observed from Réunion for the first time, and the occurrence of two species is confirmed, observed during a faunal inventory under the OBJECTIF 1000 program. Marine fishes were observed and collected off Réunion Island (France) with bottom longlines and traps in the upper bathyal zone at 1,000 m depth during a faunal inventory under the OBJECTIF 1000 program. Four species represent first records for the island: Etmopterus granulosus (Günther 1880) (Etmopteridae), Nemichthys scolopaceus Richardson 1848 (Nemichthyidae), Coelorinchus trunovi Iwamoto & Anderson 1994 (Macrouridae), and Lepidion natalensis Gilchrist 1922 (Moridae). Two species represent confirmed records for the island: Hexanchus griseus (Bonnaterre 1788) (Hexanchidae), Centroscymnus owstonii Garman 1906 (Somniosidae). New depth records are provided for C. trunovi and L. natalensis (1,000 m depth). More thorough sampling efforts would probably result in additional species never before observed in Réunion.

Five species of marine fishes are observed from La Réunion for the first time, and the occurrence of two species is confirmed, observed during a faunal inventory under the OBJECTIF 1000 program. Marine fishes were observed and collected off La Réunion Island (France) with bottom longlines and traps in the upper bathyal zone at 1,000 m depth during a faunal inventory under the OBJECTIF 1000 program. Five species represent first records for the island: Etmopterus granulosus (Günther 1880) (Etmopteridae), Nemichthys scolopaceus Richardson 1848 (Nemichthyidae), Eustomias trewavasae Norman 1930 (Stomiidae), Coelorinchus trunovi Iwamoto & Anderson 1994 (Macrouridae), and Lepidion natalensis Gilchrist 1922 (Moridae). Two species represent confirmed records for the island: Hexanchus griseus (Bonnaterre 1788) (Hexanchidae), Centroscymnus owstonii Garman 1906 (Somniosidae). New depth records are provided for Coelorinchus trunovi Iwamoto & Anderson 1994 and Lepidion natalensis Gilchrist 1922 (1,000 m depth). More thorough sampling efforts would probably result in additional species never before observed in La Réunion.

Brama brama, the Atlantic Pomfret or Ray’s Bream, is uncommon in the Mediterranean Sea and very rare in the Adriatic area. We report two historical records of this species from the northern Adriatic Sea, which represent the northernmost records in the Mediterranean. The detailed morphological data of these specimens and their comparison with available data from specimens from the Mediterranean Sea reveal the variability of the morphology of adult specimens.

Oxynotus paradoxus has been recorded in the Eastern Atlantic Ocean, from Senegal to Scotland, at depths from 92 to 1044 m. Despite being present in various Portuguese occurrence checklists, only two scientific studies reported O. paradoxus in Portugal, one off the mainland and the other off the Azores islands. During fishing campaigns onboard a commercial bottom trawler targeting crustaceans, four O. paradoxus specimens were bycaught at the SW of Portugal (SW Iberian Peninsula) at depths varying  between 742 and 1238 m. The latter is a new maximum depth record for this species, which was achieved by an adult female with a total length of 650 mm. Through this adult female, we provide new insights into the ecology and biology of this species.  Morphometric measurements were presented and compared with past studies revealing some intra-specific variability. The low hepato-, gonadosomatic and ecophysiological indices suggest that the adult female was not feeding for some time prior to collection. This study contributes to increase the knowledge of this poorly known species, using an individual approach, which is paramount when targeting rare species.

The capture of several individuals of Lepidorhombus whiffiagonis and the sighting of two individuals of Scophthalmus maximus represent the first records for these scophthalmid species from the Canary Islands. It is very likely that both species are present in Canarian waters due to natural range expansions from nearby areas. This work also contributes to the knowledge of the morphological and meristic characteristics of the southernmost populations of these eastern Atlantic cold-temperate species.
