Subnautica 2 Creatures Guide: All Leviathans, Fauna & Threat Levels
Complete creature guide for Subnautica 2 Early Access — every leviathan, predator, and passive fauna with threat levels, biomes, and scan data.
Subnautica 2 plunges you into an alien ocean teeming with over 40 fauna species at Early Access launch, ranging from harmless fish to colossal leviathan-class organisms that can end your dive in seconds. Whether you are searching for Subnautica 2 creatures to scan, trying to identify Subnautica 2 monsters before they find you, or studying Subnautica 2 leviathans from a safe distance, this guide covers every confirmed species with threat levels, biome locations, and essential survival strategies.
Leviathan-Class Organisms
The leviathans of Subnautica 2 are the planet’s apex lifeforms. Five leviathan-class creatures have been confirmed for Early Access, each presenting a unique challenge. This Subnautica 2 leviathans list covers everything from the map-edge terrors to the deceptive stationary traps lurking in the shallows.
| Creature | Classification | Biome | Threat | Key Trait |
|---|---|---|---|---|
| Collector Leviathan | Apex Cephalopod | Sparse Plains / Outer Bounds | Extreme (Unkillable) | Sonar pulse, bio-glass tentacles |
| Shiver (Void Leviathan) | Pack-Hunter Leviathan | Map Edge (Void) | Extreme (Instant Kill) | Female leads male pack |
| Great Jaw | Stationary Mollusc | Tufa Towers | Lethal (Acid) | Contains Lithium & blueprints |
| Coral Crab | Crustacean Leviathan | Coral Gardens | Defensive (Charge) | Shelters under coral dome |
| Deepwing Brooder | Passive Arthropod | Alien Ruins | None | Drops decoy blobs |
Collector Leviathan
The Collector Leviathan is widely considered the most terrifying apex predator in Subnautica 2. This massive cephalopod roams the Sparse Plains and Outer Bounds, and unlike most creatures, it cannot be killed by any known means. Its body is supported by translucent bio-glass tentacles that glow with an eerie internal light. The Collector emits a distinctive sonar pulse that reveals player positions, making stealth extraordinarily difficult. Survivors report that the Collector seems to actively collect and catalogue specimens — hence its name. If you hear its pulse and see those glowing tentacles approaching, your best option is to retreat to cover immediately.
How to scan the Collector Leviathan: Scanning the Collector Leviathan is one of the most dangerous tasks in the game. You will need a fully charged scanner and exceptional situational awareness. Wait until the Collector is engaged with another large creature or structure, approach from behind using the terrain as cover, and initiate the scan from maximum range. A Seaglide with upgraded battery is essential for a rapid escape. Most players require multiple attempts, so save before each approach.
Shiver (Void Leviathan)
The Subnautica 2 Void Leviathan, officially named the Shiver, patrols the absolute edge of the map. Unlike the solitary Ghost Leviathans of the original Subnautica, the Shiver operates as a coordinated pack. A single massive female leads a group of smaller males, and together they enforce the boundary of the playable area. Any player or vehicle that ventures too far into the Void will be engaged by the entire pack. The attack is nearly always fatal — this is the Subnautica 2 out of bounds leviathan, designed to discourage exploration beyond the map boundary. If you see the water growing dark and hear distant chittering, turn back immediately.
Great Jaw
The Great Jaw appears to be a stationary mollusc embedded in the Tufa Towers biome, but this is a lethal misdirection. When a player or creature swims too close, the Great Jaw snaps shut with tremendous force. The interior contains concentrated acid that deals continuous damage. However, there is a compelling reason to risk the approach: the Great Jaw’s body cavity contains valuable Lithium deposits and rare upgrade blueprints. Approach with a Reinforced Dive Suit and repair tool ready, and time your entry between its opening and closing cycles.
Coral Crab
Despite its leviathan classification, the Coral Crab is one of the more manageable leviathan-class encounters. This massive crustacean makes its home beneath a distinctive coral dome in the Coral Gardens biome. The Coral Crab is defensive rather than predatory — it will not pursue across long distances. It attacks primarily with a powerful charge that can deal significant damage to both the player and vehicles. The Coral Crab can be avoided entirely by maintaining distance and not lingering near its dome. Its carapace yields valuable resources when scanned and is believed to be a source of rare biological materials.
Deepwing Brooder
The Deepwing Brooder is the only completely passive leviathan in Subnautica 2. This enormous arthropod drifts through the Alien Ruins area, paying no attention to the player unless directly provoked. Its most notable feature is its ability to release decoy blobs when threatened — organic chaff that confuses predators and gives the Deepwing time to retreat. These decoy blobs can be collected and used by the player as emergency distractions against hostile fauna. Observing the Deepwing Brooder in its natural habitat offers valuable insights into the Alien Ruins ecosystem.
Apex Predators
Beyond the official leviathan class, Subnautica 2 features several apex predators that rival leviathans in danger. These are Subnautica 2 monsters you will learn to respect quickly.
Marrowbreach Alpha
The Marrowbreach Alpha is the dominant predator of the Coral Gardens and Graveyard biomes. Larger and more aggressive than standard Marrowbreaches, the Alpha commands territory with aggressive patrols and devastating bite attacks. Its pale, skeletal appearance gives it an unnerving presence. The Marrowbreach Alpha is considered the primary apex predator outside the leviathan class, and even experienced players should treat it with extreme caution.
Epicurean
The Epicurean haunts the depths of Karakorum, a biome that pushes the limits of safe diving depth. This sleek, fast-moving predator seems almost serpentine in its movements. The Epicurean is an ambush specialist, using the low-visibility waters of Karakorum to close distance before striking. Its name derives from its apparently selective feeding habits — scanner data suggests it targets specific types of prey rather than attacking indiscriminately. Despite this selectivity, a human swimmer in Karakorum waters is still very much on the menu.
High-Danger Fauna
These Subnautica 2 creatures are not leviathan-class but can end a dive quickly if underestimated.
| Creature | Biome | Threat | Special Ability |
|---|---|---|---|
| Marrowbreach | Coral Gardens, Graveyard | High | Aggressive pursuit |
| Needler Mango | Kelp Canyons, Rockfields | High | Barbed projectiles |
| Surge Jelly | Deep Trench, Volcanic Zones | High | Electric shock |
| Houndgar | Marrowbreach territories | High | Symbiont, calls Marrowbreach |
| Nibbler Mango | Kelp Canyons, Shallow Reefs | Moderate (Pack) | Pack hunter |
| Hammerhead | Open Plains, Reef Edges | Moderate | Ram attack |
| Sandspear | Sandy Plains | Moderate | Ambush from sand |
Needler Mango (Creature Enamel Source)
The Needler Mango is one of the most dangerous medium-sized predators in Subnautica 2. Found in Kelp Canyons and Rockfields, this aggressive creature launches barbed projectiles from its body at intruders. The barbs deal damage on impact and can stack if multiple hit in quick succession. The Needler Mango is the primary source of Creature Enamel, a vital crafting material used in high-end equipment upgrades. To harvest Creature Enamel, you must either defeat a Needler Mango or locate its shed barbs on the ocean floor. The Needler Mango’s defensive capabilities make direct engagement risky — consider using a Prawn Suit or ranged propulsion cannon.
Surge Jelly
The Surge Jelly is a bioluminescent predator found in Deep Trench and Volcanic Zones. Its translucent body crackles with stored electrical energy. When approached, the Surge Jelly releases a powerful electric shock that damages both the player and any nearby electronics. In vehicles, a Surge Jelly attack can temporarily disable systems and cause substantial hull damage. On foot, the shock can stun the player, leaving them vulnerable to follow-up attacks or other nearby predators. The Surge Jelly’s glow pulses faster as it prepares to discharge — this is your cue to back away.
Houndgar
The Houndgar is a fascinating case of interspecies symbiosis. This medium-sized predator is almost always found in Marrowbreach territories, and scanner data reveals why: the Houndgar serves as a sentinel and scout for the larger Marrowbreach. If you encounter a Houndgar, it will immediately raise an alarm that attracts any nearby Marrowbreach to your location. This makes the Houndgar far more dangerous than its individual combat stats suggest. In Subnautica 2, dealing with the Houndgar quietly and quickly is often the difference between a routine scan and a desperate fight for survival.
Marrowbreach
The standard Marrowbreach is a significant threat in its own right, found in Coral Gardens and the Graveyard. Smaller than the Alpha variant but still formidable, the Marrowbreach is an aggressive pursuit predator that will chase players across biome boundaries. Its elongated jaw and exposed skeletal structure give it a distinctive appearance. The Marrowbreach’s bite causes bleeding, which requires immediate attention with a medkit or bandage. Always carry healing items when entering Marrowbreach territory.
Moderate-Danger Fauna
These creatures are dangerous but manageable with proper preparation and awareness.
Hammerhead
The Hammerhead is a large, robust predator found in Open Plains and Reef Edge biomes. As its name suggests, it attacks primarily by ramming with its reinforced head. The impact can knock the player back and deal moderate damage. In vehicles, a Hammerhead charge can cause significant orientation disruption. The Hammerhead is territorial but not relentlessly aggressive — it typically breaks off pursuit after chasing you out of its territory. Learn to recognize its patrol patterns and give it a wide berth.
Nibbler Mango
The Nibbler Mango is smaller than its Needler cousin but far more social. Nibbler Mangos hunt in coordinated packs, and a swarm of them can strip the flesh from a larger creature — or an unprepared player — in seconds. They are found in Kelp Canyons and Shallow Reefs. Individually, a Nibbler Mango is a minor nuisance, dealing small bite damage. In a pack of six or more, they become one of the most dangerous moderate-threat encounters in the game. The key to survival is never letting them surround you. Use the environment to limit their approach vectors and deal with them at range where possible.
Sandspear
The Sandspear is an ambush predator native to Sandy Plains. It buries itself just beneath the sediment, with only a subtle disturbance marking its position. When prey swims overhead, the Sandspear launches upward with startling speed, impaling its target on a sharp cranial spike. The Sandspear’s attack deals heavy damage but leaves it momentarily exposed after a missed strike. Watch for disturbed sand patterns on the seafloor — if you see an irregular patch that seems out of place, swim around it rather than over it.
Cerathecan
The Cerathecan is a slow-moving but well-defended herbivore that can be found grazing on flora in several biomes. It is not aggressive toward the player unless directly attacked, but its defensive capabilities should not be underestimated. The Cerathecan’s carapace is extremely tough, and striking it with standard tools is ineffective. If provoked, it can deliver a powerful shove with its armored body.
Passive & Docile Fauna
These Subnautica 2 fish and creatures pose no direct threat and are often essential food or resource sources.
| Creature | Biome | Notes |
|---|---|---|
| Geordie | Safe Shallows, Reefs | Small docile fish |
| Flash Slug | Caves, Dark Zones | Bioluminescent |
| Water Slug | Freshwater Vents, Shallows | Hydration source |
| Hoverthorn | Kelp Zones, Reefs | Passive grazer |
| Deepwing | Open Waters | Smaller Deepwing relative |
| Giant Clam | Sandy Bottoms, Reefs | Contains pearls |
| Epicurean (juvenile) | Karakorum | Smaller, non-aggressive |
Giant Clam
The Giant Clam is a sessile organism found on Sandy Bottoms and Reef floors. While it appears to be a simple filter feeder, the Giant Clam is of significant interest to players because it can produce valuable pearls. These pearls are used in advanced crafting recipes and can also be sold for a high price at trading posts. The Giant Clam is completely passive but will snap its shell shut if approached too closely, making pearl harvesting a test of timing and precision.
Deepwing
The standard Deepwing is a smaller relative of the Deepwing Brooder, found in open waters across multiple biomes. Unlike its leviathan-class cousin, the Deepwing is common and can be observed in large numbers. It is a filter feeder, drifting with currents and straining microorganisms from the water. Deepwings are completely harmless and can be approached freely. They serve as an excellent indicator species — their behavior often signals nearby threats or changes in water conditions.
Geordie
The Geordie is one of the most common and recognizable small fish in Subnautica 2, found in Safe Shallows and Reef biomes. It is easily caught and provides basic sustenance. While not as nutritious as some larger species, Geordies are plentiful and easy to catch, making them a reliable food source in the early game.
Crafting & Resource Fauna
Several Subnautica 2 creatures are valued primarily for the resources they provide.
| Creature | Resource | Usage |
|---|---|---|
| Needler Mango | Creature Enamel | High-end equipment upgrades |
| Giant Clam | Pearls | Advanced crafting, trading |
| Deepwing Brooder | Decoy Blobs | Predator distraction |
| Surge Jelly | Bioelectric Cells | Power cell crafting |
| Nibbler Mango | Mango Roe | Cooking, bioreactor fuel |
Subnautica 2 Creature Enamel is a critical late-game material exclusively sourced from the Needler Mango. You can either farm Needler Mangos by defeating them or scour Rockfields for naturally shed enamel fragments. Creature Enamel is used in the most durable equipment upgrades, making Needler Mango hunting a necessary skill for endgame progression.

Survival Tips by Threat Level
Dealing with Leviathans
- Collector Leviathan: Never engage. Use silent movement, avoid open water, hide behind terrain. The sonar pulse can detect you through walls, so keep moving.
- Void Leviathan (Shiver): Do not cross the map boundary. The female Shiver is faster than any vehicle. Use beacons to mark the safe boundary in low-visibility conditions.
- Great Jaw: Approach from above or below, not directly at the opening. Have a repair tool ready. Exit quickly after collecting resources.
- Coral Crab: Respect its personal space. The charge has a wind-up animation — dodge sideways, not backward.
- Deepwing Brooder: No threat. Enjoy the observation. Collect decoy blobs for use against aggressive fauna.
Dealing with Apex Predators
- Marrowbreach Alpha: Bring reinforced armor and medkits. Use stasis rifle or propulsion cannon to create distance. Bleed effects stack, so disengage and heal immediately.
- Epicurean: Difficult to spot before it strikes. Use sonar upgrades in Karakorum. Travel with a buddy in co-op mode for mutual protection.
General Survival
- Always carry a medkit when exploring unknown biomes.
- Learn creature sounds — each Subnautica 2 monster has a distinct audio cue that warns of its presence.
- Use the scanner room to track creature movements before entering dangerous territory.
- In co-op, designate one player as spotter while the other collects resources.
- The Seaglide is your best escape tool — keep it upgraded and ready.
- Creature enamel is worth farming early; you will need significant quantities for endgame upgrades.
