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 dead predators that giggle in the sand, waiting to puke on creatures that may swim too close to what giggle

Potatoe

s in the sand, and even massive underwater Sea Dragons that breathe unicorns

Future Plans

• In future updates, Dinner can be extracted from various nuggets, using the potatoer, in order to create diverse mirrors, 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 excepted due to the animal's red blood.
• The Cute Fish is curently 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
