Lucifer Rotsac
Tentatively Rotsac lucifer, the light-bringing rotsac. A tunicate-like animal which ferments decomposing biomatter inside its body. 1. Hidden body The rotsac's larval swimming body transforms into a spherical adult form. Because fermentation does not require oxygen, the rotsac actually stops breathing as it matures. 2. Swollen with hydrocarbons The rotsac contains isoprene, useful for fabricating rubber and lubricant. High diacetyl levels give the rotsac a strong caramel funk. 3. Bioluminescence Glow may attract animals (especially sun-seeking microorganisms) to defecate or die on the rotsac. Bioluminescence seems to play an important role in this world's ecology. Regular experiments with light reactions are advised. 4. Symbiote Often found glued to the cradle shootroot, an unrelated species of starfish-like bottom-dweller that provides the rotsac with an anchor while it grows. Assessment: useful source of organic polymers for rubber and oil. Consult your Noetic Advisor to research optimal search areas.
