This may be an adaptation to the seawater's anomalously high viral load." — PDA upon first collection   The **Water Slug** is a small, bottom-dwelling lifeform that is incapable of significant movement. 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 will lose health.  -![Water Slug](Water_Slug.png)-  ## Appearance  -Water Slugs are small creatures with semi-translucent bodies. They have a large, long, muscular foot that is purple in color, with cyan specs seen around it. A large translucent bulb sits atop the foot, inside of which they possess a lengthy spiral gut, similar in shape to a coil. Four appendages grow out of the bulb at the back, two on each side of the body. Their color fades from cyan to yellow.+Water Slugs are small creatures with a semi-translucent body.

The Water Slug possesses a small head present at the front, which is pink in color, featuring a yellow stripe going through the middle of it. Two eye stalks spread out of the sides of the head, with small golden eyes present at the ends of them. The mouth ends with a sharp, wide beak.  -The Water Slug possesses a small head present at the front, which is pink in color, featuring a yellow stripe going through the middle.

A biological enigma that converts seawater into drinkable fresh water.+**Water Slug**  -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.+Water slug (tentatively *Seaslug hydroclast*).

Advise fabricator cook before drinking. In case of kidney problems, consider allowing the water slug to feed on your blood.   *Source: Scan a Water Slug*   ## Gallery   ### In Game   ![Water Slugs in the Shallows grass](Waterslugsstalked.png) *Water Slugs in the Shallows grass.*   ![A single Water Slug](Waterslugchillin.png) *A single Water Slug.*   ![Closeup of a Water Slug](Waterslugwoobling.png) *Closeup of a Water Slug.*   ![A Water Slug being held](Waterslugfriend.png) *A Water Slug being held.*   ### Development  -![Concept art by Alex Ries](Water_Slug_Concept_Art.jpg)+![Concept art by Alex Ries](Water Slug Concept Art.jpg) *Concept art by Alex Ries.*  -![A developmental image of an experimentally upsized Water Slug](Big_water_slug_prototype.png)+![A developmental image of an experimentally upsized Water Slug](Big water slug prototype.png) *A developmental image of an experimentally upsized Water Slug.*   ### Other   ![One of the three partial Water Slug images that was put into the Time Capsule circulation](WaterslugTimeCapsule1.webp) *One of the three partial Water Slug images that was put into the Time Capsule circulation.*   ![Ditto](WaterSlugTimeCapsule2.webp) *Ditto.*   ![Ditto](WaterslugTimeCapsule3.webp) *Ditto.*   ![An image featuring the Water Slug created for the 7th birthday of Subnautica](WaterSlugInfobox.webp) *An image featuring the Water Slug created for the 7th birthday of Subnautica.*   ## 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. *   The Water Slug can be placed on hardpoints, although it does not appear visually until the game is reloaded. This is most likely a bug.
