The trophic level (Troph) of 3.78 calculated for T. torpedo was high and pointed out that the species is a top carnivorous predator; additionally, no significant changes were recorded in Troph values related to sex, size and seasons. Muraena helena is a carnivorous species feeding on prey items representing three higher taxa, oste-ichthyans being the most common in stomach contents and such findings suggest that it should be considered as a piscivorous species. Species living in shallower waters (characterized by a narrower bathymetric range) had the most specialized diets. The caudal peduncle is about as deep as the body, and leads to a low caudal fin with an indistinct lower lobe and a ventral notch near the tip of the upper lobe. The trophic level (TROPH) of 4.47 calculated in the black anglerfish is high and indicates that the species is a top predator. and Squalus spp. Modifications which have practical value are also considered.

(2010) noted that in 267 specimens caught by bottom long-lines in the southern Adriatic, all stomachs were full; Anastasopoulou et al. 44 (4): 273-283. Cestodes of G. melastomus were linked to high turbidity and O2 levels, which increase zooplankton biomass, favouring the transmission of heteroxenous parasites. Two other species are relatively common, namely the blackmouth catshark, Galeus melastomus, and the velvet belly, Etmopterus spinax.
