A gray seal’s (Halichoerus grypus) diet largely depends on what species are available in their surrounding environment, but around the UK coastline common prey species are sand eels, whiting and flatfish. They are therefore known to dive, as these prey species are benthic dwellers meaning they are usually found on the bottom of the seabed. Common/Harbour seals (Phoca vitulin) frequently congregate in harbours, bays, sandy intertidal zones, and estuaries in pursuit of prey fish such as salmon, menhaden, anchovy, sea bass, herring, mackerel, cod, whiting and flatfish, and occasionally shrimp, crabs, mollusks, and squid.
Any fishermen who would like to donate some of their catch, this would be much appreciated. (Fish preferably)
