|---|---|---|---|---|
| Aggressive predators | 100–500 m | 5 | Observatory Ruins Depth 100 500 M Hp 1000 Aggressive | This is a wiki category page grouping all aggressive predator fauna in Subnautica 2. Aggressive predators will attack the Pioneer on sight or when provoked. The category includes Bullethead, Cerathecan, Coral Crab, Epicurean, Foureye, Hammerhead, Marrowbreach, Needler Mango, Nibbler Mango, Sandspear, Tongue Thief, Waxmoon, Houndgar, and Twin Sitaray. See individual entries for stats, strategies, and biomod unlocks. |
| Anomalies / Structures | 0 | Anomalies / Structures group — non-biological or ambiguous-origin entities. Includes Gateway Spires and other PDA-flagged anomalies. | ||
| Bloom group | 2 | Blighted Coral | The Bloom group is the collective term for all organisms associated with the Proteavirus beta infection spreading through Proteus. This includes the Bloom Canker (sessile, destroyed by Sonic Resonator/Feedback Resonator), Bloom Parasite (mobile, infects fauna), and the Angel Comb (the alien organism that grants adaptations to cure the Bloom's effects on Pioneers). Bloom-infected biomes spread via root tendrils and require active clearance to access safely. | |
| Collector Leviathan | 50–300 m | 5 | Graveyard, Root Canyon Sparse Plains, Depth 50 300 M Two Known Instances In The Ea Build One Patrolling Karakorum Metal Farms, One In The Sparse Plains Trench | The apex predator of mid-depth Proteus. A tyrant squid the size of a city block, the Collector hunts hard-shelled prey by patrolling fixed beats across the Karakorum Metal Farms and the Sparse Plains trench — and once it locks onto you, it does not lose interest. You cannot kill it. Knives ping off the carapace, sonic weapons bounce, and even high-yield charges only stagger it. Survival is about not being seen. You will usually hear the Collector before you see it: a low groaning hydraulic whine carried through the rock. If your Threat Sense pings without a visible source, surface, kill your lights, and check your sonar. |
| Coral | 0 | Coral group — diverse coral and coral-relative flora that anchor multiple biomes. Spans Shallows, Blighted Coral, Graveyard, and Plateaus. | ||
| Deepwing Brooder Leviathan | 1 | Can Appear Anywhere On The Map | A docile arthropod leviathan that drifts the open water column anywhere on the map. Picture a city-block-sized winged crustacean swimming in slow loops, releasing pulses of glowing eggs as it goes. Brooders travel in **rare packs** — usually solo, occasionally two or three together — and ignore the player completely unless attacked. The huge tearing beak is for cracking shellfish; the fatty hump on the back is brood storage. The Brooder is the friendliest large creature on Proteus. Scan it the first time you see one — sightings are not reliably predictable. | |
| Defensive | 150–500 m | 0 | Root Canyon Observatory Depth 150 500 M Defensive Herbivore | Defensive fauna grouping — non-aggressive unless provoked, but dangerous when triggered. |
| Gorgons | 0 | Gorgons group — predatory soft corals. Most species use sweeping curtain or whip-like appendages to trap small prey. | ||
| Great Jaw | 0 | Shallows, 310 M South Of Lifepod, Depth 40 M | A house-sized clam parked in the Shallows about 310m south of the Lifepod, depth ~40m. Most players' first leviathan encounter — and most players' first death. The Great Jaw isn't aggressive in the chase sense; it's a trap. The shell hangs invitingly open, the inside glints with **lithium and other rare drops**, and the appendages are slow enough that you think you can dart in and out. You can't. Once you swim past the shell rim, the valves slam, and inside you take a continuous toxin dump until your HP drains. The correct play: park outside, use the **Survival Multitool** at maximum reach to pluck loose harvestable nodes from the rim, and never cross the shell line. If you must enter (some lategame players do for the lithium core), use **Camouflage** + Dash to break for the exit the instant you take the first tick. | |
| Jellies | 0 | Jellies group (sessile) — anchored jelly relatives. Distinct from the free-swimming jellies in the fauna list. | ||
| Kelp | 0 | Kelp group — Subnautica 2's tall, frond-forming sessile flora. Most kelp species live in the Shallows. | ||
| Medical Gel Sac | 0 | Shallows, Observatory Island | The Medical Gel Sac is a bioluminescent healing resource harvested from the central node of the Acid Raion — a glowing yellow sac that provides +10 HP on direct use. It is the base ingredient for Basic First Aid Kit (1× Fiber + Medical Gel Sac) and Enhanced First Aid Kit. Safe harvest technique: strip the side Acidic Raion Pouches with the Survival Multitool first to prevent the toxic fume defense, then pick the central sac. Found under the starting Lifepod's cave. | |
| Passive | 50–350 m | 0 | Shallows Passive | Passive fauna grouping — non-aggressive mobile lifeforms. Includes most food, water, and resource drops. |
| Pylons | 0 | Pylons group — sessile pylon-form flora. The notorious Mimic Pylon is the only confirmed species in EA 1.0. | ||
| Raions | 0 | Raions group — worm-sponge colony organisms. Most Raions host predatory worm symbiotes inside a sponge-like outer membrane. | ||
| Rotsacs | 0 | Rotsacs group — fermenting tunicates. Pop on contact. Source of Rubber and Grease via the Lucifer Rotsac. | ||
| Shiver Leviathan | 5 | Dead Zones Void Very Aggressive On Player Approach | The void-barrier predator. Shivers patrol the Dead Zones around the playable map — the same role the Ghost Leviathan played in Subnautica 1. You will not meet one during normal play. You meet one if you swim past the edge of the world, and you meet it once. Unlike the Collector, the Shiver is fast, aggressive on approach, and will ram. Game files include a separate **Shiver Male** variant — players who've datamined the build report a larger, more belligerent model not yet placed in the EA world. Until then: if your compass shows you've left the map, turn around. | |
| Shootroots | 0 | Shootroots group — starfish-like sessile organisms, similar in body plan to extinct blastoids. | ||
| Sponges | 0 | Sponges group — diverse filter-feeding sponges across multiple biomes. | ||
| The World Tree | 5 | Visible From Anywhere On The Map, Towering Above The Ocean Surface Ne Of The Lifepod | Not a leviathan — a **Titan-class lifeform** that dwarfs every other creature on Proteus. The World Tree towers above the ocean surface northeast of the Lifepod and is visible from any point on the map. In EA, the **Xanadu** region surrounding it is fenced off by invisible walls; you can only look. The story end-message implies its roots are "rotten" and that saving the Tree is the planned focus of the first major expansion. Lore-wise it may be a node of the **Proteavirus / planetary consciousness** the colonists call the *Masefield* whispers — some Pioneers feel inexorably pulled north toward it, NoA actively suppresses contact. Titan-class entries imply the World Tree may not be the only one. **Easter egg:** the original Subnautica's Reaper Leviathan returns only as a **base-decoration statue** craftable from 1× Titanium via the Habitat Builder. No live Reaper exists on Proteus. | |
| Tunics | 0 | Tunics group — tunicates and salps. Includes the critical Oxygen Tunic that splits seawater into breathable O₂. | ||
| Worms | 0 | Worms group — sessile worm flora. Distinct from the predatory mobile Awnworms in the fauna list. |
