It can be used to create drinkable water. It provides -5 Food and +15 Water when consumed. The **Digestion** adaptation is required to safely consume alien lifeforms. A player without this adaptation will not receive its effect and be deducted health.   ## Appearance Water Slugs have a large muscular foot, atop of which is a largely transparent body with four backward-facing spines and a purple inner core. The head is purple and has a triangular mouth with a pair of eyestalks.   ## Behavior Water Slugs can be seen hiding within patches of seagrass where they remain motionless. When a player approaches, Water Slugs will contract their eye stems and shake.   ## On Collecting NoA will tell the player the following: > "This organism filters brine into drinkable water. This may be an adaptation to the seawater's anomalously high viral load."   ## Recipes-*(Uses item list)*+*Uses item list*   ## Databank Entry **Source:** [Scan](Scan) a Water Slug   **Water slug** (tentatively *Seaslug hydroclast*). A biological enigma that converts seawater into drinkable fresh water.   1. **Microbial fuel cell**-   Removing salt from seawater is energy-intensive. Nonetheless, the water slug does it, perhaps as a byproduct of an internal microbial reactor that feeds on waste in seawater.+Removing salt from seawater is energy-intensive.

Fresh water may be necessary for the plankton's chemistry, or it may be a prison—a way to keep the plankton from leaving.+The slug's water bulb hosts a highly productive plankton species, turning light into food.

Possible evolutionary history as a parasite or commensal, tapping a host's blood and filtering out toxins.   **Assessment:** Only nearby source of drinkable water. Advise fabricator cook before drinking. In case of kidney problems, consider allowing the water slug to feed on your blood.   ## Gallery   ### In Game ![Water Slugs in the Shallows grass](Waterslugsstalked.png) ![A single Water Slug](Waterslugchillin.png) ![Water Slug closeup](Waterslugwoobling.png) ![Water Slug held in hand like a Burger](Waterslugfriend.png)   ### Concept Art ![Concept art, by Alex Ries](Water Slug Concept Art.jpg)   ### Other ![One of the three partial Water Slug images that was put into the Time Capsule circulation](WaterslugTimeCapsule1.webp) ![Ditto](WaterSlugTimeCapsule2.webp) ![Ditto](WaterslugTimeCapsule3.webp) ![An image featuring the Water Slug created for the 7th birthday of Subnautica](WaterSlugInfobox.webp)   ## Trivia * The Water Slug was the first Subnautica 2 creature to be shown, being partially revealed in three images put into circulation in Subnautica's Time Capsules and subsequently added as a custom emote to the official Discord server. * The Water Slug cannot be cooked, unlike its counterpart in the first two games, the [Bladderfish](sn1:Bladderfish). * Despite being the namesake of the databank’s Water Slugs category, the Water Slug itself is currently listed in a separate, molluscs category, making the [Flash Slug](Flash_Slug) the only organism listed under the Water Slugs category. * The Water Slug can be placed on [hardpoints](Hardpoint), although it does not appear visually until the game is reloaded. This is most likely a bug.
