The Water Slug (Seaslug hydroclast, "water-splitting sea slug") is a remarkable defensive mollusc that converts seawater into drinkable fresh water — making it a critical survival resource. Found throughout the Shallows, the Water Slug is the easiest and most accessible water source in early game. Bioscanning it (with the Bioscanner) unlocks the Water Secretion passive biomod (+5 water every 3.5 minutes, stackable in inventory) — described as the easiest passive biomod to obtain in the game.

- Water Slugs are passive and abundant — no risk involved in bioscanning them.
- They are everywhere in the Shallows; you will encounter them naturally on any resource run.
