The False Fission Drum is an unusual kelp-like lifeform. It does not currently appear in game.

Databank Entry

Tentatively Polymephycite tympanum. Not animal, plant, or fungus, but a fourth category of complex life analogous to Earth protists.

1. Central structure

The central stipe is a biopolymer akin to chitin or keratin held upright by a beard of air-filled sacs (pneumatocysts).

2. Dual feeding strategy

Photosynthesis is the primary nutrient source, but cave-dwelling drums subsist on dissolved nutrients.

3. Reactor glow

Adults develop a large bioluminescent swelling called a sprangia. Its blue light precisely mimics the Cherenkov radiation of a nuclear fission reactor immersed in seawater.

Assessment: further investigation required. Await further updates.

Buy me an oxygen tank 😄
