Overview
Aster Scyllid (Megahecaspid aster). A colony of shell-forming, algae-like organisms analogous to Earth's haptophytes or coralline algae. Composed of hecaspids with fatty or starchy centers enclosed in calcium carbonate shells. Internal bacterial colonies convert sunlight, chemical energy, or radiation into nutrition. The colony interior functions as a reservoir of high-density food storage — colloquially called a 'sea tuber.' A positive ecological indicator suggesting thriving biodiversity.
