We report the first record of two teleost species from two archipelagos in the western equatorial Atlantic. We recorded the occurrence of Cantherhines pullus (Ranzani, 1842) (Monacanthidae, Tetraodontiformes) from the Fernando de Noronha Archipelago, a group of volcanic islands 345 km off the northeastern coast of Brazil. We also report the first regional record of Hemiramphus brasiliensis (Linnaeus, 1758) (Hemiramphidae, Beloniformes) from the Saint Peter and Saint Paul’s Archipelago, which is a small and isolated group of rocky islands 520 km from the Fernando de Noronha Archipelago on the Mid-Atlantic Ridge.

The distribution and ecology of the isopod family Haplomunnidae Wilson, 1976 are reviewed with new records given for Thylakogaster Wilson & Hessler, 1974, Mid-Atlantic Ridge and east Pacific Ocean, and for Munella Bonnier, 1896, Mid-Atlantic Ridge and the eastern Atlantic near the African coast. The specimens of these two genera, collected from Lucky Strike (Mid-Atlantic Ridge), are the first record of the family from hydrothermal vent habitats. The systematics of the Haplomunnidae is updated and the synonymy of Aryballurops Gamô, 1983 with Haplomunna Richardson, 1908 is proposed. Thylakogaster lobotourus Wilson & Hessler, 1974 is redrawn from the first known intact specimen and additional description of the appendages is provided.

Seven scalloped hammerhead sharks (Sphyrna lewini) were satellite tagged around the Saint Peter and Saint Paul Archipelago (SPSPA), located at the equatorial Mid-Atlantic ridge, to investigate their vertical and horizontal movements. All sharks remained in the surroundings of the SPSPA over the course of the 120-day monitoring period, suggesting a high degree of medium-term site fidelity. During this period, scalloped hammerhead sharks covered a wide extension of the water column, ranging from the mixed layer to the mesopelagic zone. All sharks remained in warm (>22°C) shallow layers most of the time, but also dove to depths greater than 150m, mostly at night, eventually reaching 728m (5.6°C) on two occasions. This study contributes important, novel information on the habitat use and movement patterns of scalloped hammerhead shark in Atlantic equatorial oceanic waters. It also highlights the potential of protecting key, large oceanic areas as a useful tool for the conservation of this endangered species.

The Saint Peter and Saint Paul Archipelago (SPSPA) are located close to the Equator in the Atlantic Ocean. The aim of this study was to assess the spatial variations in the copepod community abundance, and the biomass and production patterns of the three most abundant calanoid species in the SPSPA. Plankton samples were collected with a 300 µm mesh size net along four transects (north, east, south and west of the SPSPA), with four stations plotted in each transect. All transects exhibited a tendency toward a decrease in copepod density with increasing distance from the SPSPA, statistically proved in the North. Density varied from 3.33 to 182.18 ind.m−3, and differences were also found between the first perimeter (first circular distance band) and the others. The total biomass varied from 15.25 to 524.50 10−3 mg C m−3 and production from 1.19 to 22.04 10−3 mg C m−3d−1. The biomass and production of Undinula vulgaris (Dana, 1849), Acrocalanus longicornis Giesbrecht, 1888 and Calocalanus pavo (Dana, 1849) showed differences between some transects. A trend of declining biodiversity and production with increasing distance from archipelago was observed, suggesting that even small features like the SPSPA can affect the copepod community in tropical oligotrophic oceanic areas.
