on that logic crocodiles are partly aquatic, Galcion. A creature that lives on land around water, but can swim, is allowable so long as the DF doesen't let the user keep the ability to swim. Besides, OP world zoans would have to be limited to species we have actually seen and had named. Otherwise, how would we know they even exist?

So in short, your point stands, but With those to considerations I think they're allowable.
