The diet of a harp seal is centered on small fishes, primarily including:

  • Capelin (Mallotus villosus)
  • Arctic cod (Boreogadus saida)
  • Polar cod (Arctogadus glacialis)1

In addition to these fish, harp seals consume numerous invertebrates. Contrary to some common beliefs, they rarely feed on the commercially significant Atlantic cod.1
