Bladderfish

3D Model

Extracted with Unity Asset Explorer

The Bladderfish is a small fish that lives in shallow waters of both The Crater and Sector Zero of 4546B. The bladderfish has a strange body plan, with no mouth, 6 water jets, and 2 external sacs. The creature survives by sucking in water by expanding the sacs, pulling water in through its jets, filtering out bacteria to eat and oxygen to breathe. Then it pushes out the excess water through its jets, moving it forward. The fish is a great source of oxygen and purified water.
