Molluscs from a shallow-water whale-fall and their affinities with adjacent benthic communities on the Swedish west coast
We conducted a species-level study of molluscs associated with a 5-m long carcass of a minke whale at a depth of 125 m in the Kosterfjord (North Sea, Sweden). The whale-fall community was quantitatively compared with the community commonly living in the surrounding soft-bottom sediments. Five years...
