It can be used to create drinkable [water](Water).   ## 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.   ![Water Slug](Water_Slug.png)   ## 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 in fear.   ## 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 The Water Slug can be processed to produce: *   [Water](Water)   ## 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.   2.  **Fresh water reserve**     A hydrophobic plastic bulb that protects the slug from rapid dehydration by saltwater.   3.  **Plankton farm**     The slug's water bulb hosts a highly productive plankton species, turning light into food. Fresh water may be necessary for the plankton's chemistry, or it may be a prison—a way to keep the plankton from leaving.   4.  **Vampiric aura**     The water slug's developed beak has a sharp cutting surface. 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](https://subnautica.fandom.com/wiki/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.
