We used fishery-dependent data and generalized additive models to examine the environmental characteristics associated with the presence of M. mobular in the eastern Atlantic Ocean. Results revealed that the distribution of M. mobular is significantly associated with seasonal upwelling systems in coastal and pelagic areas. Our model predicted the presence of the species in areas where there is evidence of its occurrence, such as the Angolan upwelling system and the coast of Ghana. In addition, our model predicted new hotspot areas, including locations around the Mauritanian upwelling system, the Guinea coast, offshore Ghana and the south coast of Angola and Brazil, where sample sizes are limited. Those areas, as well as the environmental preferences depicted by the model, provide valuable information about the habitat and ecology of the spinetail devil ray. Future research lines derived from this study, as well as its limitations, are discussed. Furthermore, in light of our results we discuss the improvements that are needed to contribute to the conservation and management of this vulnerable species. specialized Spinetail devil ray Species distribution modeling Bycatch species Tropical tuna Eastern Atlantic Ocean Conservation ATLANTIQUE 034 040 43 447-460 2020 1863-5407 https://www.documentation.ird.fr/hor/fdi:010080956 10.3354/esr01082 1863-5407 [F B010080956] https://www.documentation.ird.fr/hor/fdi:010080956 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-03/010080956.pdf IRD - Base Horizon / Pleins textes 2021-04-01 2025-02-24 fdi:010080956 fre
