Creatures
What kind of fauna to expect, broken into behavior categories. Names and specific stats fill in after we see them on screen.
Behavior categories to expect
Drawn from the original Subnautica and Below Zero patterns, with real names and stats added after launch.
| Category | What it looks like | What to do about it |
|---|---|---|
| Peaceful drifters | Small fish, jellyfish, schools that ignore you | Scan fodder and food. Most of the early scan list will be this category. No threat unless you grab them aggressively. |
| Defensive fauna | Reactive but not actively hunting | Bite you if you swim through them, sting on close pass. Original Subnautica had Crashfish and Stalkers in this category. Watchable but not chasing you. |
| Mid-tier predators | Sandshark-equivalent, Bonesharks, reef-zone hunters | Will track and bite. Manageable with a knife or detour. The first thing that teaches you to time your dives. |
| Leviathan-class | Massive, territorial, can one-shot a player | Series staple. Reapers in Subnautica 1, Glow Whales and Shadow Leviathans in Below Zero. Subnautica 2 trailers have hinted at a void-zone equivalent. Avoid until vehicle upgrades are in. |
| Scan-only entities | Story-relevant, not really "creatures" | Architecture, pods, ancient relics, things that exist for narrative purposes. Scan, do not fight. |
| Co-op interaction | Behavior may change with more players nearby | Untested. Original Subnautica had no multiplayer, so creature AI in groups is genuinely new territory. We will update once we see how aggro splits. |
