Description

The Ghost Leviathan has a soft, bioluminescent, transparent outer membrane covering a muscular, blue, inner body which features many darker blue stripes, 12 yellow, bioluminescent eyes as well as six, possibly vestigial fins on the torso section. A small sail sits on top of the head, and two long structures protruding from either side of its head which bear similarities to the cephalofoil of a hammerhead shark. It has a rectangular mouth with a glowing barbule lure beneath. Its long body tapers to a point.

The outer body is transparent, making the smaller, inner body visible. The inner body is long and thin, and covered in pulsating, bioluminescent orange stripes with many orange tipped protrusions ending with blinking bioluminescent orange glows. Unlike the outer body, the inner body has a distinct, thin neck joining the head and body. As the leviathan moves through the water, it leaves trails behind it.
