I just came up with an extremely unlikely idea of how the Amatsu is able to fly through the air. Possibly, it doesn't stay by making itself lighter or through the use of lighter than air filled sacs, but by being extremely heavy and dense. Maybe, it is able to fly because it can make its own gravity by being an extremely heavy amount of matter packed into a small space, like a black hole. So, it could then use this personal bubble of gravity to then fly around as it wishes.

The reason for the fins, it might possibly get its food not by predation, but by intimidation. All those fins on its body, instead of being aerodynamic, may be used to make itself look far bigger and more impressive than it truely is in order to scare off other predators from a kill that they made. it could then easily go in and eat an already dead animal with little to no effort.

Personally, the first theory that I had came up with seems preposterous, but my second one, to me at least, could possibly be true.
