this is the grey seal, Kegelrobbe, gråsäl , halli or harmaahylje

and now I understand your estimate of 200 kg for the first one. the bulls can have up to 300kg what make them the biggest european carnivore before the european brown bear.
Pusa hispida is the ringed seal, Ringelrobbe, vikare or norppa.

I think on your nordic cost it replace the common or harbor seal

we have here in the south. never eat seal meat before but think it could be similar to whale meat I had from norway in the past regularly.
the eskimos never complain about it.
