What they will encounter is a large, mostly transparent creature, whose skull and a small portion of the body is bright white/lightblue. From a distance, in the darkness, it looks no larger than your average shark, although the four red eyes and the snake-like split in the bottom jaw might cause some alarm. As it gets closer, the ghostly blue body comes into focus, revealing large manta-ray like fins. These and the long, eel-like body gives the creature a look like a deep-sea dragon once you are able to see the rest of it.

It's able control the currents in the water and change the water pressure, as well as use water as a weapon as well.
