Bioluminescence

Bioluminescence is a type of illumination created by many Flora species and all but two species of Fauna in Subnautica. Most bioluminescent life forms cannot generate light bright enough to help the player with night time navigation.

Trivia

 * The Stalker and Lava Lizard are the only two fauna having no bioluminescent glands.
 * The Lava Lizard can don a glowing lava shell, but this is not bioluminescence. The glow comes from the lava, not through a biological function of the lava lizard itself.
 * 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.
 * The Rockgrub is the only creature in Subnautica with bioluminescence that can light up the surrounding terrain.
