Shadow Leviathan

The Shadow Leviathan is a future species of Leviathan-class predator.

Appearance
The Shadow Leviathan has an elongated black body with smooth skin and a pair of rows of 37 small red spots running from the neck to just before the tip of the tail. Below each row side is a shorter row of seven circular holes that only runs down the neck. The head is composed of a triangular shield with three pairs of small D-shaped red eyes with large black pupils, the pair closer to the middle being smaller than the rest. A long vertical slit lined with translucent blue "teeth" comprises the mouth. Directly below the mouth is a transparent sac in which recently consumed prey is stored.

Nine pairs of large limb-like clawed mandibles run down the sides of the mouth, with the bottom pair being angled downwards to better grasp larger prey items. The seven upper pairs of graspers have "teeth" along the inside edge. Four more pairs of these appendages can be seen down the body, decreasing in size as they get closer to the tail to the point that the final pair are little more than a small spine. This gives the impression that these grasping appendages once served as legs in a distant ancestor but have since been re-purposed into their current form.

Propulsion comes from the large fins on the tail portion of the Shadow Leviathan's body. Though lacking a tail fluke, a large fin is present around halfway down the body on both the dorsal and ventral sides. With the ventral fin having two smaller fins in front of and behind it. The tail ends with a red point.

Design
The tail portion of the body is very similar in appearance to the black ghost knifefish and the row of holes on the neck resemble the gill openings possessed by lampreys. The mouth and mandible design was based on the heads of arrow worms.
