The concept literally depicts the other creature though. They even have the light-emitting organs (I forgot what they are called) found on the original creature, and the picture features the working title of the creature, which is not "leech".

Edit: The info is about this dev update: https://store.steampowered.com/news/app/892970/view/3673284490062877605?l=english

but the concept does not tell you about its size at all. consider that. just because the design if similar doesnt mean the size is keep that in mind. and it beeing ashland waters only well. i somehow doubt that they can be the same size given ashland waters simply arent large enough very often to spawn such big enemies commonly.
