“…As N. cepedianus is thought to predominantly inhabit shallow coastal waters (Ebert, 2002), finding this species 1000 km from the continental N. cepedianus has also been found in the remote archipelago of Tristan da Cunha, >2700 km from the nearest South African coastline (Caselle et al, 2018). These findings, together with those of the present study, indicate that N. cepedianus also occurs in offshore habitats, supporting the notion that this species is capable of undertaking large-scale movements (Ketchum et al, 2017;Williams et al, 2012) and spends more time in deeper waters (Stehfest et al, 2014) Currently, very little is known about H. griseus and N. cepedianus populations in the ETP apart from data gleaned from by-catch reports in Peru and Ecuador's coastal region. Thus, documenting and defining their occurrence and ranges is critical to formulating informed conservation strategies and identifying key habitats for their survival (García et al, 2008;Hearn et al, 2014).…”
