 SCS: Harp Seal (Phoca groenlandica)
Sealing interests are however calling for photographers, whose presence is already severely restricted and who have been attacked by sealers, to be banned from recording the hunt altogether.
For the 2001 sealing season Norwegian vessels were allocated hunt quotas of 15,000 adult harp seals on the West Ice (2 non-suckling pups deemed equal to 1 adult) and 5,000 adult harp seals on the East Ice (2.5 non-suckling pups deemed equal to 1 adult).
Seal meat from the hunt was previously sold as food to fur farms but this has not occurred for the last few years as the farms are importing cheaper dried meat from Germany, many seal carcasses being left to rot near processing plants as a result.

Hawaiian monk seals are normally found on the leeward (southwest) sides of the northwestern Hawaiian islands, and occasionally sighted in the main Hawaiian islands.
Monk seals are also assumed to prey on pelagic (open ocean) species, but only because the monk seal is known to travel long distances in the open ocean.
All monk seal species appear to be sensitive to disturbance, and early habitat exclusion by humans throughout their range may have exacerbated their decline.
