Creature Database — Subnautica 2 Fauna: Species, Threats & Behavior
Low threatUpdated 2026-06-02
The Subnautica 2 creature database documents every fauna species available in the Early Access build. From harmless filter-feeders to apex leviathan predators, this creature database covers habitat biomes, threat ratings, behavioral patterns, scan analysis data, and whether each species can be raised in alien containment. The creature database is organized by threat level so you can quickly identify which species require caution and which are safe to approach for scanning or harvesting.
Passive and docile creatures
The Subnautica 2 creature database categorizes approximately 20 species as passive or docile. These include the Paddlefish (Safe Shallows herbivore, drops edible fish), the Glowcrab (Kelp Caves detritivore, drops luminous chitin for batteries), and the Floater (Grass Plateau filter-feeder, can be attached to objects to reduce weight). Passive creatures in this creature database can be scanned without threat and most can be bred in alien containment for a renewable food or material source. The Pegasus Ray, a new species in Subnautica 2, glides through the Thermal Spires and emits a calming pheromone that reduces nearby creature aggression for 30 seconds when harvested.
Aggressive and dangerous creatures
Aggressive species in the Subnautica 2 creature database include approximately 12 actively hostile creatures. The Crushclaw (Thermal Spires) ambushes from sandy floors — listen for the burrow sound cue. The Crabsnake (Jellyshroom Caves) strikes from within jellyshroom stalks and can grab the player if too close. The Boneshark (Grass Plateau trenches and Thermal Spires) is attracted to light and will attack vehicles. The Lava Lizard (Lava Corridor) spits molten projectiles and guards thermal vent resource nodes. This creature database recommends the stasis rifle or perimeter defense system for dealing with aggressive species — direct combat with tools is not recommended due to their high health pools.
| Species | Biome | Threat | Harvest | Containment? |
|---|---|---|---|---|
| Paddlefish | Safe Shallows | None | Edible fish | Yes |
| Crushclaw | Thermal Spires | Medium | Crushclaw hide | Yes |
| Crabsnake | Jellyshroom Caves | High | Venom gland | No |
| Boneshark | Grass Plateau / Thermal Spires | Medium | Boneshark tooth | Yes |
| Shadow Leviathan | Deep Zone | Extreme | Leviathan scale | No |
| Lava Lizard | Lava Corridor | High | Thermal sac | No |
| Glowcrab | Kelp Caves | None | Luminous chitin | Yes |
Leviathan-class threats
The apex of the Subnautica 2 creature database are the leviathan-class predators. The Reaper Leviathan returns from the original game, patrolling the border between the Grass Plateau and the Deep Zone. The new Shadow Leviathan is exclusive to Subnautica 2 — a serpentine predator that blends into the dark water of the Deep Zone and uses bioluminescent lures to attract prey. Both leviathans in this creature database can destroy the Seamoth in two hits and damage the Prawn Suit significantly. Leviathans cannot be killed with standard weapons — the intended approach is avoidance using sonar and terrain cover. Scanning a leviathan requires the extended-range scanner module and careful positioning behind terrain while it patrols away from your location.
FAQ
- How many creatures are in the Subnautica 2 creature database?
- The Early Access build of the Subnautica 2 creature database includes approximately 35 species, of which roughly 12 are aggressive and 2 are leviathan-class. Future updates will add more species to reach the planned total of approximately 80.
- Can I breed aggressive creatures in alien containment?
- Some aggressive species like the Crushclaw and Boneshark can be raised from eggs found in their native biomes. Leviathans and cave-dwelling species like the Crabsnake cannot be contained — they require open water environments.
