The Crimson Ray is a large, passive ray species and a close relative of the Ghostray. It lives exclusively in the Inactive Lava Zone and Lava Lakes.

Appearance

In terms of body shape and size, the Crimson Ray is identical to the Ghostray; however, it has major differences in biology and coloration:

  • The creature's body is fully opaque and appears to possess thick skin.
  • The top side of the creature is predominantly dark red in color with a few lighter patches, whilst its underside is pale yellow in color.
  • Its rows of gills emit a yellow, bioluminescent glow.
  • The Crimson Ray also has yellow goat-esque eyes instead of the cyan ones of the Ghostray.

Behavior

Crimson Rays will aimlessly swim around and will flee if approached by the player or a shark-classified fauna. Crimson Rays are curious and will swim towards small classified fauna. Despite being located in a cave, they swim slower at night and are harder to scare.

One of the largest rays on the planet, displaying generally docile behavior.

  1. Thick Scaling: Scales formed on the skin protect this ray from extreme temperatures, allowing it to survive in areas unpopulated by competing scavengers.
  2. Forward-mounted Eye Sockets: Suggests a predatory evolutionary history, left behind long ago.
