Fauna

This seems new This article contains information that is updated for the latest Experimental Version of Subnautica. Players using stable mode may find this information inaccurate.

Fauna are life forms found all over the world of Subnautica, from the deepest darkest depths to the vibrant safe shallows

There are a large variety of fauna, ranging from eels that use bioelectricity to incapacitate predators and hunt, to heavily armored predators that hide in the sand, waiting to ambush any creatures that may swim too close to what lurks in the sand, and even massive underwater Sea Dragons that breath fire!

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.
