Fauna

These are the life forms found all over the world of Subnautica, from the deepest darkest depths to the vibrant Safe Shallows.

There is a large variety of fauna, ranging from eels that use bioelectricity to incapacitate predators and prey alike, to massive Sea Dragons that spit chunks of boiling lava.

Future Plans

 * In future updates, DNA can be extracted from various fauna, using the transfuser, in order to create diverse serums, each with unique effects and implementations in various upgrades.

Trivia

 * Fauna were intended to posses inherent attributes, that would have caused them to exhibit unique behaviors. These included, e.g., "Fertile" (occasionally lay eggs that can be hatched), "Alpha" (attacked the player if other creatures were killed by the player in the immediate vicinity), "Complex" (specimens take longer to scan), "Greater" (specimens are of larger size and weight), ... Whether these attributes are currently implemented or will be implemented in future updates is unknown.
 * As of the Dangerous Creatures update, all fauna have yellow blood. Before this update, fauna had red blood. This is due to the ESRB giving Subnautica a higher rating than expected due to red blood.
 * The Cute Fish is currently the only obtainable pet fauna in development, which is obtainable through the debug console and will only be granted to players whom purchased the early access version of subnautica
