Overview
Coral Dome (Coral geodesica). The defining feature of its shallow biome. A colony of polyps — small jellyfish-like organisms that produce limestone skeletons — absorbing dissolved CO₂ and converting it to solid limestone, making coral domes critical for climate regulation. Outer surface harnesses sunlight through zooxanthellae; inner polyps sting and capture prey. As the dome grows, it recycles limestone from its interior. Expels mineral waste as nodes of quartz — a critical resource. Assessment: vital to planetary health; do not damage unnecessarily.
