With the last seasons the aquatic exploration acquired a greater importance, but that aquatic exploration feels a bit empty. This is not something new, it is a recurring claim in the community since the first steps of the game.
We have sharks and some fish, I think it's a good time to add stingrays, crabs!!!, sea turtles, octopus, etc. Even some of these examples are already present in the official Art Book.
Thanks.
