Flora
16Acid Raion
A colony of worms living inside a shared membrane, probably a sponge. Uses weak acid to digest prey.
Aeroshell Sponge
A glowing sponge (tentatively *Symphon aeroshell*) that resembles the cone of a heat shield on atmospheric entry.
Amphora Sponge
A sponge adapted to colonize — and create — air pockets.
Apocalypse Sponge
An unassuming button-shaped sponge that may be an omen of mass extinction.
Aster Scyllid
A colony of shell-forming, algae-like organisms analogous to Earth's haptophytes or coralline algae.
Awnworm
Awnworm (*Ventworm awn*). Dwells in hot, mineral-rich water, where its plumes collect hydrogen sulfide and other minerals from the environment. Can survive near-boiling temperatures.
Branching Coral
Databank autogeneration interrupted. Script hook found in allocated memory. Executing. Unpacking archived data... "Nahema, voice log, go. If you're listening to this and you don't have lead poisoning, I am very jealous. If you're listening to this and you do have lead poisoning, I'm sorry I couldn't figure it out in time. Mea culpa. "This is a typical Protean coral. It works differently than Earth coral. The gross morphology is a branching tree, like some species of Earth's extinct Acropora. We all call it coral because we know the word. But the difference matters. "On Earth coral are basically tiny jellyfish living in stone houses. The jellyfish sting prey. They also let zooxanthellae live with them, houseguests who make food from the sun. "On Proteus...I think what we're seeing here is actually a sponge acting as a landlord. The sponge makes a house. It rents space to these tiny coral polyps, which sting prey and capture sunlight as energy for the sponge. "I think the sponge used to be in charge. But eventually the coral polyps got so good at their job that the sponge stopped pumping water and just lived off rent from the coral polyps. And to keep its tenants alive, it evolved a rocky shell — like Earth's sclerosponges. "If I'm right, we should see other coral-sponge pairs that have worked out different deals. Each deal suited to a particular ecological niche."
Cabbage Shootroot
A robust bottom-dwelling organism anatomically similar to a plastic starfish, or to an opened variety of Earth's extinct blastoids.
Cage Gorgon
A predatory soft coral named for its resemblance to Earth's gorgonians.
Cherimoya Rotsac
A tunicate-like animal which collects alcohol from decaying matter to produce a creamy, flavorful mucus.
Coral Dome
The defining feature of its shallow biome.
Cradle Shootroot
A basket-shaped organism (tentatively *shootroot cunabulum*) with no clear Earthly analog. Anatomically similar to a plastic starfish, or to an opened variety of Earth's extinct blastoids.
Curtain Gorgon
A soft, predatory coral akin to Earth's gorgonians, especially the Venus fan.
Dangling Salp
A sticky, suspension-feeding predator that captures organisms from the current.
Donut of Worms
An organism (tentatively *Raion donut*) that resembles an Earthly anemone or ceriantherian, but is actually a sponge occupied by a colony of predatory worms.
Donut, No Worms
Donut of worms (tentatively *Raion donut*) without visible worms.
Leviathan
3BFJ
, the behemoth finger-legged jelly. A massive specimen with no Earthly analog.
Collector Leviathan
Enormous cephalopod predator (tentatively *Tyrannoteuthis phobocoeus*, tyrant squid of fearful curiosity). Feeds on hard-shelled, heavily defended prey. Solitary but highly intelligent. Likely a deep-sea creature.
Deepwing Brooder
, the titanic wing-segmented cup of plenty. An enormous arthropod leviathan with a huge tearing beak and a payload of fatty deposits, which it uses to both feed and protect its eggs.
Fauna
5Bluemoon
Databank entry coming soon.
Bullethead
, the armored squid dart. A swarm predator that attacks by ramming and penetrating its prey. Capable of *Caught script hook in allocated memory for command >> generate-databank "Bullethead" >> echo \memory-carve -signature=0xSEABEEF5 >> restore-databank* "I saw their eyes first. Bright yellow eyes, down the inside of the lava tube. I killed the motors and the floods, signaled Iso and Mel to grab the handholds, and held my breath. For a minute I thought we'd ride clean through. Then the current pulled the Tadpole into an outcrop and at the sound they all just—went off. Like bottle rockets. Back and forth, up and down, everywhere. One of them lodged in the port hull just aft of the canopy and I saw, very clearly, that it was a squid, completely plated in armor. They hit you tail first, hard enough to punch into titanium. Incredible. Do you think they run on compressed air? Or do they burn something? The hull alarm went off — I tried to blink the floods to confuse them — but Mel and Iso's blackboxes were already crying. The noise seemed to attract them. Apparently they like to get stuck in wounded prey and wait until you bleed to death, then go to work on your carcass. So by the time I got back to Habitat there wasn't much left of Iso and Mel for Iso and Mel to recycle." —Tsewangiin "Ruby" Anar, "When I Didn't Die"
Cerathecan
"Our PDAs point to organisms like the cerathecan and exclaim 'behold: the road not taken'. On Earth, seed shrimp are tiny slime-dwellers; on Proteus they grow huge. But just as easy life in our decontaminated bases deafens us to the call of Proteus, easy analogies blind us to the truth. The map from Earth is not only wrong, so is its basic dogma. Evolution does not follow roads here." —Anita Gottschall, *The Way Away Home* *Exile cerathecan*, the horn-cupped exile. A mysterious carnivore and deposit feeder with no clear Earth analog except the tiny ostracod (seed shrimp).
Coral Crab
An enormous crab (tentatively *Ostrakonskelos anaktoraphore*, hard-legged palace-bearer) that hides among coral domes.
Dead Coral Crab
The remains of a large crustacean (dead) and a coral dome (bleached, dead). The crab may have used the dome as a portable shelter.
Subnautica 2 Creature Overview
Creatures in Subnautica 2 are not just threats to avoid. They define how each biome feels to move through, what kinds of risks are waiting in open water or tight terrain, and which areas are safer for gathering, scanning, or establishing longer exploration routes.
A useful creature database should therefore do more than list names. It should help players understand what kind of lifeform they are looking at, how dangerous it is, what habitat it prefers, and whether it is mostly a hazard, a passive ecological presence, or something that matters for resources and route planning.
Creature Types
The main category split exists because creatures influence exploration in different ways. Leviathans represent large-scale danger and route pressure, fauna covers moving animals that can threaten, ignore, or interact with the player, and flora includes rooted or colonial life that can still affect visibility, chemistry, harvesting, navigation, or local safety.
How To Read Threat And Habitat Tags
Threat and habitat tags are most useful when read together. A creature's danger level only matters in context: some species are open-water problems, some dominate narrow terrain, and some stationary organisms become dangerous because of their placement, effects, or how they change the immediate environment around resources and travel lines.
Subnautica 2 Creatures FAQ
Why separate Leviathans from other creatures?
Because leviathans usually change exploration at a much larger scale. They are not just stronger encounters, they often redefine how safe a route feels, how much distance you can cover comfortably, and whether a biome can be treated as transit space or active danger space.
Should flora stay in the same database as fauna?
Yes. In a survival game like Subnautica 2, rooted organisms still matter because they can block movement, alter local conditions, create hazards, or shape where useful materials and safe paths are found. Leaving flora out would remove part of the actual biome logic.
What should this page prioritize first?
The most important information is usually habitat, threat level, behavior, and practical exploration value. A creature page becomes much more useful once it explains whether the species changes scanning strategy, gathering safety, escape planning, or general movement through a biome.
Related Exploration References
Threat behavior becomes more useful when it is connected to nearby resources, planned builds, and the route you are actually preparing to run.
