The sampling station was located in Salobreña,
Granada province, southern Spain (36º 44’ 39’’N; 3º
36’ 10’’W). The specimens were collected at depths between
3 and 10 m, on a human-disturbed rocky bottom
made up of blocks and pebbles, which was gently sloping
and mainly colonized by the so-called “biocenosis of
infralittoral photophilic algae” (Pérès & Picard, 1964).
