Subnautica 2 Creatures by Biome
The named Subnautica 2 fauna at Early Access, split into leviathans, aggressive predators, defensive creatures and passive fauna - and which biomes they turn up in. Behavior classes follow the official wiki, and each row carries a confidence tag so you know what is confirmed.
Read this first
Behavior classes (Passive / Defensive / Aggressive) below follow the official Subnautica 2 wiki Lifeforms page. Defensive creatures only retaliate when provoked - they are not free kills, but they are not active hunters either. Subnautica 2 is in active Early Access with more fauna arriving across the planned 2-3 year window, so re-check the wiki after each patch.
Leviathans
The biggest organisms in the ocean, all confirmed on the official wiki. Most are aggressive, but the Deepwing Brooder is passive and the World Tree is a passive Titan-class structure that is not yet reachable in Early Access.
-
Collector Leviathan
ConfirmedAggressive leviathan-class
Confirmed on the official wiki. A large multi-tentacled cephalopod predator that broadcasts sonar. Treat its exact hunting range as patch-dependent.
Reported zone: Open shelf / deep (verify in-game)
-
Shiver Leviathan
ConfirmedAggressive leviathan-class
Confirmed on the official wiki. An aggressive pack hunter (a 'shiver') that inhabits the Void beyond the Early Access barrier and devours intruders. Do not enter the Void unprepared.
Reported zone: The Void (beyond EA barrier)
-
Great Jaw
ConfirmedAggressive leviathan-class
Confirmed on the official wiki. An enormous sessile ambush predator that works like a giant venus flytrap, trapping and neurotoxin-killing prey. Reported in the Dolerite Spires at the southwestern map edge.
Reported zone: Dolerite Spires (SW edge)
-
Deepwing Brooder
ConfirmedPassive leviathan-class
Confirmed on the official wiki. A passive, migratory leviathan that roams the map perimeter in groups of three - docile, not a predator. It moves fast, so you need mobility upgrades to scan it.
Reported zone: Migratory (map perimeter)
-
World Tree
ConfirmedPassive Titan-class (not yet reachable)
Confirmed on the official wiki as a passive, sessile Titan-class organism - among the largest living things in the setting. It sits beyond the world border (Xanadu, past the Great Trench), so it is not yet accessible in the current Early Access build.
Reported zone: Beyond world border (EA-locked)
Predators and passive fauna
Smaller fauna grouped by the official wiki Lifeforms behavior class. Aggressive creatures hunt you; Defensive creatures only fight back when provoked; Passive creatures are safe to scan and harvest. Anything not yet on the official wiki is flagged separately.
Aggressive (active threats)
ConfirmedClassed Aggressive on the official wiki Lifeforms page - they will pursue and attack. Electric Geordie is hostile/electric. Biome and aggression range still shift between patches.
Defensive (retaliate when provoked)
ConfirmedClassed Defensive on the official wiki - not active hunters, but they fight back if attacked or cornered. Do not treat them as free harvest, and do not treat them as apex predators either.
Passive and small fauna
ConfirmedClassed Passive on the official wiki Lifeforms page - harmless to scan or harvest. Tongue Thief is a passive crustacean despite the name.
Not yet on the official wiki
PredictedNamed in community roundups but not found on the official wiki Lifeforms page at the date shown, so behavior is unverified. Re-check after patches.
What lives in each biome
The creature angle on our source-tracked biomes - what you meet and what you harvest from fauna there, not coordinates. For exact positions use the coordinates atlas and interactive map.
| Biome | Confidence | Fauna notes |
|---|---|---|
| Twisty Bridges (shallows) | Confirmed | Small passive fish such as Bladderfish near the drop-pod area; no confirmed large predator in the immediate spawn shallows. |
| Kelp / vegetation forest | Community | Vegetation-zone predator activity is reported around the dense kelp, and the jellyfish forest contains Stilt Orbs whose Necrolei Cysts are an early Strong Acid source. Verify the predator roster in-game before farming. |
| Sparse Plains (worm zone) | Confirmed | Open low-cover area shown in official footage with a large burrowing threat and Collector Leviathan activity. The lowest-cover, highest-risk fauna zone of the early map. |
| Crash Zone | Predicted | A large-predator patrol is inferred here from the Subnautica 1 Aurora pattern. Treat any Leviathan patrol as unconfirmed until players map it. |
| Deep / toxic biomes | Community | Toxic-zone fauna and large deep threats are community-reported around the deep alien-tech nodes. Names and behaviour are unsettled; bring deep-dive prep before scouting. |
Sources and methodology
Confirmed creatures are named in the official Subnautica 2 wiki and across multiple independent guides. Community labels come from Reddit, Discord and video documentation where names are not yet settled. Predicted entries are inferred from Subnautica 1 and Below Zero patterns or from unrevealed teasers, and are marked as not confirmed. Because the game is in active Early Access, every creature roster - including this one - should be treated as a snapshot that can change with the next patch.

- Community creature roundups (Beebom, GAMES.GG, wikily.gg) cross-checked for name overlap.
