Void Whale

The Void Whale is the largest known organism to be found within the Void.

Physical Appearance
Void Whales are, in essence, the whales of the In-Between: their bodies mirrored that of Baleen Whales of Earth, but its side fins have evolved into a set of large wing-like fins much like those of Rays, and are used in a similar function along with its large, multi-finned tail.

Behavior
Very little has ever been studied on the Void Whales in this concept. It can be assumed that, according to their anatomy, they are gentle giants who only feed off of much smaller organisms.
