Crab Feces

MineRaw

Overview

Coprolyte-like deposit of excreta. Extreme energy density; suitable as bioreactor fuel. Found in the Coral Gardens biome. Used as a crafting ingredient in Biofuel Block (from Crab Feces), requiring 2 per craft at the Processor. This positions Crab Feces in the equipment progression, where crafted tools and gear expand the player's exploration range, survivability, and resource-gathering efficiency. Raw minerals like Crab Feces fuel the entire crafting ecosystem in Subnautica 2. Every tool, vehicle component, and base module traces its material lineage back to raw resources gathered from the ocean floor. Prioritizing Crab Feces collection during routine exploration builds a reserve that smooths out the resource spikes of mid-game construction projects.

Tips & Strategy

Look for Crab Feces deposits on cave walls, cliff faces, and the seafloor — mineral outcrops are most concentrated in areas with rocky terrain.

Concentrated in the Coral Gardens — plan dedicated gathering runs to this biome when your supply runs low.

Needed for Biofuel Block (from Crab Feces) (2x per craft) — collect at least 4 to allow crafting with a safety margin.

Keep Crab Feces organized in labeled storage near your primary crafting station — maintaining an ordered inventory prevents wasted time searching for materials during urgent crafts.

All recipes using Crab Feces are crafted at the Processor — store your supply near this station for maximum efficiency.
