[@Shovel] Indeed, all mundane animals were spawned during the fight between sarhush and saries, so one can reasonably assume that sea creatures also exist. Now, how well they have adapted to the nearby corrupted ocean is another thing entirely... [@Cmmelody]

The sea creature are more aggressive during normal time, they will revert beck to a calm state during the clear ocean. The marine life with god's blessing or patron's power will be more immune to corruption, to what extend is up to the blesser. By the way, I imagine the clear ocean water as well as uncorrupted fish might be in some of the alchemy formula, to the annoyance of those poor alchemist :lol. Maybe the corrupted water and fish would even be in another separate formula....
