Another thing from the " " it specifies that Grimm only attack humans and there creations (Im guessing buildings etc) though animals have been know to start fights with Grimm just reminded me of the LightBringer books series book 3 Brocken Eyes where a Massive fully grown sperm whale attacks a Sea demon.

Would sea grim be able to survive with sharks and certain species of whales like the sperm whale which is known to be terratorial attacking them? My bet is that they would have to survive in rivers and lakes then migrate to the sea once they have become sufficiently old to survive or the ability to swim so deep that they would not be able to reach them.
