Well, probably some leviathan-esque monster, some type of sea-dragon maybe. Now that I think about it, there needs to be more sea-dragons. There could also be some forgotten gods, ar maybe an Eldritch Abomination. Of course it can't all be heavy-hitters. Maybe some subspecies of crab-girls and mermaids. I could imagine some really pale hikkomori type mermaids living there, and maybe an Angler-Fish Girl.
