Feeding of the deep-water fish Helicolenus dactylopterus (Delaroche, 1809) in different habitats: from muddy bottoms to cold-water coral habitats

The present study represents the first documentation of the trophic spectrum of the deep-water teleost fish Helicolenus dactylopterus in two basins of the central Mediterranean (Northern Ionian and Southern Adriatic) and the first attempt to compare the diets of this deep-water teleost fish between two different habitats: flat muddy seabed and cold-water coral (CWC) habitat. 346 stomachs were collected on muddy bottoms and 352 in CWC habitats....
