Deep-sea biodiversity at the extremes of the Salas y Gómez and Nazca ridges with implications for conservation

Nazca ridges [64–67], and input from regional taxonomic experts (Figs 2 and 3). The maxi- mum number of individuals of each species in a single video frame (MaxN), rather than a total tally per deployment, was recorded to ensure that individuals were not double counted [68].
