Subnautica 2 leviathan species list
As of the Phase 2 update, there are seven Subnautica 2 leviathan species in Early Access. Three return from the original Subnautica — Reaper, Ghost, and Sea Dragon Leviathans — with updated AI and new patrol routes. Four new Subnautica 2 leviathan species debut in Subnautica 2: the Mantis Leviathan (a fast, aggressive predator in the Kelp Forest biome), the Deep Stalker (a blind leviathan that hunts by vibration in the Deep Zone), the Void Wraith (found at the map edge), and the juvenile Sand Serpent (a burrowing leviathan in the Sandy Plains). Each Subnautica 2 leviathan species behaves differently and requires a distinct avoidance strategy.
| Species | Biome | Aggression | Max Depth | Threat Level |
|---|---|---|---|---|
| Reaper Leviathan | Dunes, Mountains, Crash Zone | Extreme | 300 m | Critical |
| Ghost Leviathan | Lost River, Grand Reef | High | 900 m | High |
| Sea Dragon Leviathan | Inactive Lava Zone | Extreme | 1300 m | Critical |
| Mantis Leviathan | Kelp Forest, Deep Kelp | High | 400 m | High |
| Deep Stalker | Deep Zone, Abyssal Trench | Medium | 1100 m | Medium |
| Void Wraith | Crater Edge (Void) | Extreme | N/A | Critical |
| Sand Serpent (Juvenile) | Sandy Plains, Dunes | Low–Medium | 200 m | Low |
Survival tips against leviathans
Each Subnautica 2 leviathan species requires a different approach. For the Reaper Leviathan, the standard strategy is to use a Perimeter Defense upgrade on your Seatruck or Prawn Suit. The Mantis Leviathan is faster but has less health — aggressive players can kill it with a Prawn Suit Drill Arm. The Deep Stalker is blind but senses vibration: moving at slow speed or stopping completely makes you invisible to this Subnautica 2 leviathan. The Void Wraith is inescapable if you go past the crater edge — it is meant as a soft barrier, not a combat encounter. The Sand Serpent is the only Subnautica 2 leviathan species that can be outrun on foot (Seaglide speed is sufficient).
Leviathan rank and classification
Subnautica 2 introduces a leviathan classification system. Small leviathans like the juvenile Sand Serpent have 2,000–3,000 health. Medium Subnautica 2 leviathan species like the Deep Stalker have 5,000 health. Large Subnautica 2 leviathan species like the Mantis Leviathan have 8,000 health. Ultra-large species like the Reaper, Ghost, and Sea Dragon Leviathans have 10,000+ health. This Subnautica 2 leviathan ranking helps you decide whether to fight or flee. As a general rule, if the Subnautica 2 leviathan species is classified as ultra-large, you should always flee instead of engaging.
