Glow Whale

The Glow Whale (Placeholder name) is a future fauna species of Subnautica: Below Zero.

Description
The Glow Whale appears to have convergently evolved with the baleen whales of Earth, sharing a very similar morphology and feeding behaviour. Though it lacks baleen plates entirely.

Appearance
The creature's ventral side is white with ridges running from the head to the flukes. Also on the ventral side are a pair small fins directly below each flipper. Interestingly, the patch of skin being touched by the diver in the concept art has lit up.

The dorsal side appears grey and two transparent horn-like appendages protrude backwards from behind the head. There are two dorsal fins, with the front fin larger than the rear fin.

The flippers are large and sail-like, composing of a narrow muscular protrusion with a thin luminescent membrane connected to it. At the very tip of the fin it tapers off into a tendril, at the end of which is a glowing pod. The lower back has prominent ridges and spots, similar to those of a whale shark.

The eyes have a yellow iris and a large black pupil, situated in front of each eye is an orange, luminescent pill-shaped organ set into a hollow the skin. Some barnacles and vegetation can be seen on various parts of the body.

Trivia

 * It was designed by Pat Presley during pre-production for Subnautica but was never implemented. It has since been repurposed for Below Zero.
