The present study presents an updated taxonomical classification for these groups and reports new data on their distribution and density in canyon areas and adjacent open sedimentary slopes. Samples were collected from 220 trawls and 36 ROV dives conducted in the Blanes, Palamós and Cap de Creus canyons and their adjacent slopes (north-western Mediterranean), between 850 and 3000 m depth. The most abundant Phylum was the Echinodermata, representing 52.9% of the total invertebrate density (calculated as ind.•km-²), and 48.6 % of the total invertebrate biomass (calculated as kg.•km-²). Five rare species for the Mediterranean were found: a sipunculid, 3 echinoderms and 1 carnivore ascidian
