PDA entry
- Coral geodesica. The defining feature of its shallow biome.
- 1. Coral analog
- Like Earthly coral, the dome is a colony of polyps, small jellyfish-like animals that secrete a limestone skeleton. This process uses dissolved carbon dioxide from the seawater: corals are therefore an important method of climate regulation, since they transform atmospheric carbon into hard limestone.
- 2. Dual feeding strategy
- The dome's outer surface feeds on sunlight, using photosynthetic symbiotes known as zooxanthellae. As the dome grows, the colony clears its interior, recycling the limestone for reuse. Polyps on the inside of the dome hunt with stinging tentacles.
- 3. Mineral expulsion
- As the dome grows, it collects and expels mineral waste, creating nodes of quartz.
- 4. Critical ecosystem element
- The dome corals help regulate global climate and provide a breakwater, reducing erosion in their shallow surroundings. The domes capture nutritious sediments from sea currents. Pioneers should prioritize a survey of coral health.
- Assessment: critical source of quartz. Vital to the local ecosystem.
