Feeding habits of northeast atlantic harp seal (Phoca groenlandica) along the summer ice edge of the Barents Sea
Stomachs from 58 harp seals Phoca groenlandica from the northern parts of the Barents Sea were collected between August 20 and September 5 1987. Fiftysix of the stomachs contained identifiable contents. The amphipod Parathemisto libellula was the most common food items, found in 98% of the sea1 stom...
