Ebony Blister-wing

True to its name, the Blisterwing has ebony dark-brown skin, and boasts large gas-filled bladders on its and body used for flying in air. The tail of the Ebony Blister-wing splits up into two appendages, what Wayne Barlowe calls "twin tail booms". It is unknown what the diet of this giant animal is. It may be microflyers, creatures living in air, or it may be capable of photosynthesizing. On Earth, there are many animal species with that ability, like the sea slug Elysia chlorotica.
