Bloom Plankton are a microscopic fauna species that was cut from the original Subnautica and may be repurposed for Below Zero


Bloom Plankton are small, found only in groups and usually invisible, only becoming visible when they are "charged" with light. Their colour can be altered by shining different types of light onto them. Shining a flashlight into a group of Bloom Plankton will cause them to glow bright white in colour; if a flare is thrown near a group of Bloom Plankton they will glow red in color, this color will be retained for a few moments before they become invisible again.

When charged, they can become a light source and will light up their surroundings.
