Subnautica 2 Creatures — Fauna Tracker
32 Subnautica 2 creatures and lifeforms are now tracked in this Subnautica 2 wiki with threat levels, biome locations, scan data, and survival notes from current public lists.
Current creature coverage
This page now includes the launch creature set surfaced by current lifeform databases: Leviathans, hostile fauna, passive fish, jellies, crustaceans, salpapods, and mango-group creatures. Individual pages keep exact scan text and route claims conservative until they are checked in game.
Leviathan Warning: 5 Leviathan-class entries are tracked. Collector Leviathan and Deepwing Brooder and Shiver Leviathan and Coral Crab and Great Jaw need current-build checks for spawn zones, pursuit range, and reliable escape tactics.

Leviathans
Apex and large-scale encounters that need the most careful route planning.
LEVIATHANLeviathan
Collector Leviathan
A massive cephalopod-like leviathan with four sprawling tentacles, each serving a distinct mechanical function. Found roughly 20,000–25,000 units horizontally from the starting area. Unlike most predators, the Collector will pursue you relentlessly across biome boundaries — it never gives up the chase.
LEVIATHANLeviathan
Deepwing Brooder
A leviathan-class apex predator with broad, wing-like pectoral fins that generate powerful pressure waves during pursuit. The Deepwing Brooder earned its name from observed behaviour of clustering around organic anchor points — likely a form of territory anchoring or reproductive protection. Its pressure wave attacks can disorient navigation instruments and destabilise Tadpole hull integrity.
LEVIATHANLeviathan
Shiver Leviathan
An immense leviathan-class predator that patrols the Abyssal Trench in long, sweeping arcs. Its elongated silhouette and bioluminescent fringe make it visible from distance — but visibility is no guarantee of safety. The Shiver Leviathan possesses a thermal detection system capable of locating warm-bodied prey through dense water columns, and pursues with relentless endurance once locked on.
LEVIATHANLeviathan
Coral Crab
A massive crustacean that holds a leviathan-class designation despite inhabiting the relatively shallow Coral Reef. The Coral Crab is slow in open water but compensates with a territorial lunge reach that extends far beyond its body size. Its armoured carapace shrugs off most environmental damage, and its claw strikes deal significant hull damage to the Tadpole. Coral Reef explorers are often surprised to encounter a leviathan-tier threat this early.
LEVIATHANLeviathan
Great Jaw
A large cephalopod-class organism that occupies the transition zones between mid-depth and deep biomes. The Great Jaw ambushes prey by pressing its body flat against dark rock faces and remaining nearly motionless. A bioluminescent lure on its dorsal surface pulses slowly to attract prey — a subtle but effective trap for distracted Pioneers following light sources in low-visibility environments.
Predators
Hostile or dangerous fauna with attack, shock, grab, or ambush behavior to document.

Salpapod
Electric Geordie
A larger variant of the common Geordie that has developed a bioelectric discharge organ in its ventral mantle, fuelled by mineral-rich thermal vent runoff. Electric Geordies cluster near vent chimneys where their metabolic requirements are most efficiently met. The discharge stuns nearby prey and temporarily disrupts battery-powered tools — making close encounters more dangerous than the threat level alone implies.

Fish
Hound Gar
A sleek, fast-moving predatory fish with elongated jaws and a distinctive ridge of dorsal scales. Hound Gars are pack hunters — lone individuals are rarely encountered in isolation, and the presence of one confirms others are in the immediate area. They use coordinated flanking to cut off escape routes before converging on their target.

Crustacean
Sandspear
A large canyon-dwelling crustacean with a spear appendage twice its body length. The Sandspear buries itself in loose sediment at canyon junctions, remaining completely concealed until prey crosses its engagement zone. Its spear penetrates standard Pioneer suit material and reaches significantly farther than the creature's body size suggests — canyon-floor routes through Crag Canyons are dangerous until you learn their positions.

Jelly
Surge Jelly
A highly electrified jelly native to thermal vent zones, where it absorbs electrical charge from mineral-rich vent chimney runoff and releases it in concentrated bursts. A direct Surge Jelly discharge is capable of shutting down Tadpole electronics temporarily and draining battery-powered hand tools to zero — compounding the inherent dangers of the thermal zone.

Crustacean
Tongue Thief
A fast-moving crustacean with an extensible tongue-like grasping organ that targets occupied hands. The Tongue Thief targets the Pioneer's held tool specifically — a successful grab knocks the active item to the seafloor. In pack encounters, multiple sequential grabs can compound a dangerous equipment scatter situation, forcing the Pioneer to retrieve items while under continued attack.
Crustaceans and Mango Lifeforms
Shell, crab, sand, and mango-group lifeforms with scan and material-use notes.

Crustacean
Anemone Crab
A medium-sized crustacean that carries clusters of sea anemone on its shell — a symbiotic arrangement that provides camouflage among coral while the anemones receive transport to richer feeding zones. When threatened, the anemone clusters discharge a mild neurotoxin causing brief disorientation. Most encounters are incidental; the Anemone Crab rarely initiates contact unless cornered.

Crustacean
Cerathecan
A spiny crustacean with a serrated carapace and elongated spear-like forelimb appendages used for feeding and territory defence. The Cerathecan is a slow-moving sessile feeder that does not actively hunt Pioneers but reacts with a rapid spear strike when its feeding territory is entered. It does not pursue past its territory boundary.

Crustacean
Jetocaris
A jet-propelled crustacean capable of remarkable short-burst acceleration using a compressed water bladder in its abdomen. The Jetocaris uses this propulsion both to escape predators and to deliver surprise strikes at competitors intruding on its food territory. The strike itself causes minimal damage, but the momentum can send the Pioneer into nearby environmental hazards.

Mango
Marrowbreach
A bulbous, slow-moving mango-group organism that feeds on dissolved minerals through root-like absorption structures trailed behind its body. Considerably larger than related Mango species, the Marrowbreach defends its absorption trails with a mildly toxic mucus secretion. The body itself poses no hazard; contact with the trailing absorption structures causes brief disorientation.

Mango
Nibbler Mango
A small, social mango-group organism that travels in loose groups and nibbles on coral and organic matter. The Nibbler Mango is not a predator but becomes habituated to human presence near base structures and food drops, repeatedly nibbling at anything that appears to be food — including tools, cables, and the Pioneer's hands.
Jellies, Slugs, and Salpapods
Soft-bodied lifeforms, electric variants, and low-profile scan targets.

Jelly
Hycean
A large translucent jelly organism with a broad bell and trailing stinger filaments that extend up to 6 metres behind its body. The Hycean is not an active predator — it drifts passively in current corridors, and the filaments cause toxic contact damage to anything that swims into them. Pioneer suits provide partial protection; sustained contact causes increasingly serious debuffs.

Jelly
Jelly Ring
A ring-shaped gelatinous organism with a hollow toroidal body that pulses rhythmically to propel itself through open water. The Jelly Ring emits a concentrated electrical field at its ring aperture to paralyse small prey drawn through the centre. Pioneers report brief paralysis of swimming muscles and tool-use on direct contact with the ring structure.

Water Slug
Flash Slug
A small, fast-moving slug variant that propels itself with rapid water-jet expulsions. The Flash Slug emits a brilliant bioluminescent burst when startled — a predator defence mechanism that can momentarily affect Pioneer vision in low-light cave passages. Entirely passive; no aggression documented under any condition.

Salpapod
Geordie
A common salpapod found throughout mid-depth biomes, drifting in loose clusters through active current corridors. Geordies are passive filter feeders that draw nutrients from the water column. They are ecologically significant as primary prey for multiple higher-threat species — their presence in a zone indicates the broader food web is active.

Salpapod
Quadrate
A compact salpapod with four defined flat wall surfaces that give it a distinctly geometric appearance compared to rounded reef species. The Quadrate feeds by drawing water through pores in its flat faces. Groups produce a distinctive clicking sound pattern — an ambient audio cue that Pioneers learn to associate with safe, low-threat current corridor zones.
Passive Fish
Food, water, scan, and route-density entries for starter survival loops.

Fish
Bullethead
A torpedo-shaped predatory fish with a blunt, heavily reinforced cranium used in stunning charges. Bulletheads hunt alone, using fast lateral bursts to build ramming momentum before committing to a charge run. The charge is a single-direction commitment — if it misses, the Bullethead requires several seconds to decelerate and reorient before another attempt.

Fish
Epicurean
A mid-sized ambush predator that buries itself in loose sediment or tucks behind reef structures, waiting for smaller fish to swim into range. The Epicurean strikes with a rapid upward lunge and retreats immediately to cover. It will opportunistically strike at Pioneers who hover near its concealment point — not territorial behaviour, but simple predatory reflex.

Fish
Needler Mango
A spined ambush fish that conceals itself among coral and rocky formations with needle-like dorsal spines extended as a territorial warning. The Needler Mango has critical wiki significance: tooth clusters around its territory yield Creature Enamel when harvested with the Sonic Resonator, and scanning the organism itself unlocks the Dermal Garden Biomod.

Fish
Bluemoon
A small bioluminescent reef fish with a distinctive blue crescent marking on each flank. Bluemoon schools congregate near coral formations at dusk, creating an easily recognisable navigational landmark. They scatter on fast approach but reform within seconds. Fully passive; edible after Digestive Incompatibility is cured.

Fish
Four Eyes
A flat-bodied reef fish with two pairs of eyes oriented to provide simultaneous upward and downward vision — an adaptation for spotting both aerial and depth threats. Four Eyes feed on surface invertebrates and are passive toward Pioneers. Experienced explorers note that a sudden Four Eyes school scatter in a calm reef zone reliably precedes a predator approach.

Fish
Halfmoon
A shallow reef fish recognisable by its crescent-shaped tail fin. The Halfmoon is a grazer that feeds on coral polyps and soft-bodied organisms, congregating near large coral formations. It is one of the first fauna a Pioneer encounters after landfall, and one of the most reliably available food sources once Digestive Incompatibility is cured.

Fish
Harvestmoon
A golden-scaled reef fish that gathers in dense clusters near bioluminescent coral at night. The Harvestmoon's metabolic chemistry produces nutrient-dense tissue — it provides significantly better hunger restoration than comparable passive reef fish. Experienced Pioneers target Harvestmoon specifically for long-dive food provisions.

Fish
Pneuma
A large-finned reef fish with a visible gas-filled swim bladder through its translucent flanks. The Pneuma hovers motionless in open water columns, feeding on floating organic particles. Entirely passive; notable for producing an audible resonant sound when its bladder expands — a familiar ambient sound in healthy reef zones.

Fish
Twin Sitaray
A paired-fin reef fish that uses synchronised twin-fin undulation for precise hovering and slow navigation through tight coral structures. Twin Sitarays are passive grazers that rarely flee from approach, making them one of the easiest early Scanner targets in the game. They hold position long enough to be cleanly scanned, which makes them ideal for building Scanner usage habits in the first hour.

Fish
Waxmoon
A slow-moving disc-shaped reef fish covered in a thick waxy secretion that protects it from minor abrasion and chemical exposure. The Waxmoon is the primary prey species for most Coral Reef predators, meaning its presence in unusually high concentrations is a reliable inverse threat indicator — dense Waxmoon clusters often mean predators are also concentrated nearby.
Other Lifeforms
Entries that need a more precise current-build class.

Herbivore
Hammerhead
A round-bodied herbivore covered in radiating fin-spines, giving it a sunburst silhouette. Completely non-aggressive — it grazes on kelp and algae and will flee from the player. Safe to approach and easy to scan.

Passive Fauna
Waterslug
A small, docile creature found throughout shallow areas. Completely harmless and will flee when approached. Useful early scan target to practice the scanning mechanic.
