Water Slug Creature Guide and Details | Subnautica 2

A small herbivore that is often found within seagrass to stay away from predators.

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 still does it, perhaps as a byproduct of an internal microbial reactor that feeds on waste in the seawater.

[2] Fresh Water Reserve

The creature has a hydrophobic plastic bulb that protects it from rapid dehydration caused by saltwater.

[3] Plankton Farm

The water slug's bulb hosts a highly productive plankton species that converts light into food. Fresh water may be essential for the plankton's chemical processes, or the bulb may function as a prison to prevent the plankton from leaving.

[4] Vampiric Aura

The water slug's developed beak has a sharp cutting surface. It is possible that its evolutionary history involves acting as a parasite or commensal, tapping a host's blood and filtering out toxins.

Assessment: Only nearby source of drinkable water. It is advised to use a fabricator to cook the water before drinking. In case of kidney problems, consider allowing the water slug to feed on your blood.

Waterslugs are useful early-game creatures. Make sure to collect them as a water source, both by themselves, and through synthesis with the Fabricator.
