PDA entry
- A basket-shaped organism (tentatively shootroot cunabulum) with no clear Earthly analog. Anatomically similar to a plastic starfish, or to an opened variety of Earth's extinct blastoids.
- 1. Animal anatomy
- The flattened, fibrous 'leaves' are the arms of an animal loaded with photosynthetic symbiotes. The central structure houses a digestive system and a hard, sticky cradle (the cunabulum). A second ring of arms grows into the seabed, seeking crevices in the rock.
- 2. Preferred symbiote
- The cradle is an exchange site with a symbiotic partner (such as the lucifer rotsac). Spectrogenetic analysis suggests the cradle shootroot is younger than the rotsac. It may have originally parasitized free-floating lucifer rotsacs, before evolving a niche as an anchor: providing a refuge and minerals to the rotsac in exchange for a share of the rotsac's fermented food.
- 3. Plastic fibers
- Although it lacks the true cell walls of Earth plants, the cradle shootroot strengthens its tissues with bioplastic fibers. Too tough to cut by hand, they could be severed by a cutting tool.
- Assessment: tough fibers could be used to synthesize fabric, possibly food.
