Always active while equipped·Early Access: equip 1 Active (default Shift on PC) and 1 Passive at a time.
How to unlock
Scan Coral Crab with the Bio Scanner.
Bio Scanner required
Most BioMods require the Bio Scanner attachment (green glow while aiming). Parts are found in the late-game zone; craft at a Modification Station. Standard Scanner scans do not unlock BioMods—you must re-scan donors with the Bio Scanner.
Where to scan
About 380 m east of the Life Pod in a hydrothermal transition zone. Exit your vehicle to wake the crab. It also drops feces usable for food crafting.
In-game effect
Doubles water gained from all consumable sources (e.g. a +40 water item restores +80).
Tips
Strong passive for reducing how often you need to craft or find water items.

Bioscans and biomods are easier to plan when you can compare scan targets, genome costs, and the creatures behind each unlock.
Use creatures for habitat and threat context, the Crafting Planner for material needs around the Biolab, and the interactive map to plan scan routes before spending genomes.
