Piscene Wyverns aren't fish at all; they can breathe air. All wyverns have two legs and two wings (or fins, in this case). I know what you mean about practically every monster being called a Wyvern, but that's because they all are. Even Brute Wyverns are simply Wyverns that have lost their wings due to evolution.
