The Bullet Head is one of the small, catchable fish you encounter almost immediately after climbing out of the Lifepod in Subnautica 2. It swims in the shallow biome directly beneath your starting position, making it one of the earliest reliable food sources once your character can actually digest native life.
Where Bullet Head Fish spawn
The starting biome under the Lifepod is the primary habitat. You don't need a vehicle, a tank upgrade, or any tool to reach them. Drop into the water, look around the seafloor and mid-water column, and you'll see small fish drifting between rocks and plant growth.
The same area also contains anemones that drop fibrous pulp and a second species of small edible fish, so a single dive can stock you with both protein and the ingredients for oily salad.
How to catch one
Catching is done by hand. No multitool, knife, or trap is required for these small fish.
Step 1: Swim down from the Lifepod into the shallows and locate a Bullet Head. Approach slowly so it stays within reach rather than darting away.
Step 2: Get close enough that the interact prompt appears, then click to grab it. The fish goes straight into your inventory.
Step 3: Return to the Lifepod's Fabricator to cook it. Cooked fish restores roughly 25 to 40 food points per piece. Raw is edible but restores less and chips away a little health.
Make it edible first: the digestion problem
Native life on this planet is biologically incompatible with your character at the start of the game. Picking up a Bullet Head triggers a "digestive incompatibility" warning, and eating it raw or cooked will do nothing for your hunger meter until you unlock the Digestion adaptation from an Angel Comb.
The relevant Angel Comb sits roughly 160 meters north-northeast of the Lifepod, near Anita's Blackbox. A black cable runs along the seafloor and leads straight to the site. Interact with the glowing pink core of the large blue plant to gain the Digestion adaptation. From that point on, cooked Bullet Head and oily salad both count as real meals.
Food values and uses
| Item | Source | Food restored |
|---|---|---|
| Nutrient Block | Lifepod storage (x3 at start) | +40 |
| Cooked fish (Bullet Head) | Fabricator | +25 to +40 |
| Raw fish (Bullet Head) | Eaten directly | Lower, with small health cost |
| Oily Salad | Fibrous pulp at the Fabricator | +20 |
Hold your three starting Nutrient Blocks in reserve until your food meter dips below 60. Each block restores 40 points and the meter caps at 100, so eating one when you're already full simply wastes the difference.
How to confirm everything worked
Two checks tell you the loop is functional. First, your inventory should show a Bullet Head after a successful catch. Second, after touching the Angel Comb core, eating cooked Bullet Head should visibly raise the yellow food meter in the lower-left corner instead of showing the incompatibility warning. If the meter doesn't move, you haven't acquired the Digestion adaptation yet, and you need to return to the Anita's Blackbox site.
Once the Digestion adaptation is active, the shallows below the Lifepod become a renewable pantry. Later in the game, salt and Sugar of Saturn open up higher-value recipes, but for the opening hours of Subnautica 2, hand-caught Bullet Head cooked at the Fabricator is the most efficient way to keep the hunger meter topped up.
