Images showing the geomorphology of the sampling sites. A Bajo de Emirio (BE); it is a wall formed by large stepped rocky platforms superimposed on each other; B Los Arcos (LA); a heterogeneous vertical wall formed by encrusted rocks of small size that form cavities and crevices; C Majahuitas (MH); there is a smoother slope with small and medium-sized boulders. In all three localities, there are important accumulations of sediments, also different species of sea fans and sponges are common. Photographs by Armando Perez Otegui.
