TriviaEdit

  • The Stalker and Lava Lizard are the only two fauna having no true bioluminescent glands.
  • Bioluminescence is used by many real-life animals for counter-illumination, luring prey, attracting mates, confusing predators, mimicking other animals, communication, and as a warning to would-be predators.
