I do know kipodan is both an animal name and a flower name.
Another name of this kind: Tukiyam - a kind of sea bird (I think the english name is alca, not sure).
Anyway, the academy was very lazy with sea mammals - we have kelev-yam, arye-yam, pil-yam and others. No unique hebrew names (even ´dolphine´came from greek=.
And I saw the giant otters (Lutrot anak) last week in Manu reserve.

Thanks. I forgot the whale.
