“…Submarine canyons are environmentally important areas for the megafauna dynamism and the ecology of multiple species. These structures have an effect on the deep-sea species assemblages both within the area itself and on the neighboring open slope (Romano et al, 2017;Tecchio et al, 2013), which populations may be interconnected due to eggs and larval dispersal by water current dynamics, as for the case of Aristeus antennatus (Clavel-Henry et al, 2020). Some benthic communities undertake seasonal and ontogenetic migrations between the canyon area and the open slope, which are detected by observation of the specimen sizes and the distribution of fishing effort throughout the year, as for the case of A. antennatus (Sardà et al, 1997;Sardà et al, 2003a;Tudela et al, 2003) and Merluccius merluccius (Stefanescu et al, 1994).…”
