For someone whose name is Fishgoth (this is not my real name), I don't fold too many things that are very fishy. Never the less, I do have a few designs that are piscine, crustacean, molluscoid or otherwise represent frequently submerged creatures. For the pedants out there, this gallery will also include fresh-water organisms.
