Hammerhead
A round-bodied herbivore covered in radiating fin-spines, giving it the sunburst silhouette that earned its name. Despite the predator-style appearance, the Hammerhead is one of the safest creatures in Subnautica 2 — non-aggressive, flees from the player, and ideal for scan practice across multiple biomes.

Core facts
Behaviour
Hammerheads graze on kelp and algae beds. They flee from the player at any close distance and do not retaliate when struck. Multi-biome distribution means you do not need a specific destination to scan one — they show up across shallow and mid-depth zones, often near food vegetation.
The sunburst silhouette can confuse new players into treating the Hammerhead as a predator. Behaviour is the more reliable signal: passive grazing posture, no aggro on approach, and a clean flee animation when threatened.
Scan and sample tips
- The flee window is short. Approach low and slow rather than head-on; the Hammerhead aims its sunburst at threats, which adds an awkward angle for the scanner.
- Multi-biome distribution makes the Hammerhead a "scan of opportunity" rather than a destination scan. Tag one whenever you cross paths.
- Keep biomod claims separate from scan behavior until a source row is verified.
- Pair a Hammerhead scan with a Waterslug scan in the Kelp Forest for two of the safest early data entries.
Questions people ask
Is the Hammerhead dangerous in Subnautica 2?
No. Despite the menacing silhouette, the Hammerhead is a passive herbivore that grazes on kelp and algae. It flees from the player and does not retaliate even when struck. Threat level is the minimum 1 / 5.
Where do Hammerheads spawn?
In multiple biomes ranging from shallow Kelp Forest grazing areas to mid-depth transitions. The "Multiple Biomes" tag suggests a generalist distribution — a useful trait for filling scan-data gaps without a specific biome run.
Why is it called a Hammerhead?
For the sunburst silhouette: a round body covered in radiating fin-spines that splay out like a hammerhead profile when viewed head-on. The name reflects body shape, not the predator association from Earth biology.
Is there a DNA Modification linked to the Hammerhead?
Not confirmed at a publishable standard. The Hammerhead is a safe scan target, but any specific biomod claim still needs a Bioscanner unlock check, current-build confirmation, and a source row before it belongs in the catalogue.
