Concha genus
Description
Highly specialised complex extremophiles that have developed protective and sturdy motile shell structures. These open and close based on the suitability of the current environmental conditions. The shells are an organic structure with an excreted inorganic insulated and sometimes reflective casing that help the organism maintain homeostasis. The internal organisms, which are remarkably tough in their own right, are only exposed for metabolic and reproductive purposes.
Minimum distance between two genetic samples: 150 m
Conditions of occurrence
- Planets with thin Ammonia, Nitrogen, Water or Carbon Dioxide atmosphere
- Maximum gravity: 0.27
Atmosphere type | Species |
---|---|
Ammonia | Concha aureolas |
Carbon dioxide Carbon dioxide rich | Concha labiata (< 190 K) Concha renibus (180 K - 195 K) |
Nitrogen | Concha biconcavis |
Water, Water-rich | Concha renibus |
Concha aureolas

Description
These concha are found on worlds with nitrogen-based atmospheres. Their rounded rock-like structure splits part to extend long stalks topped with loops.
Conditions of occurrence
- Planet with thin Ammonia atmosphere
- Maximum gravity: 0.27

Concha biconcavis

Description
This concha species resembles a ridged, bisected egg until they crack in half, allowing a thin stalk to sprout from its fleshy insides. This is covered with cloughnut—shaped pods that create locations for chemical exchange.
Conditions of occurrence
- Planet with thin Nitrogen atmosphere
- Maximum gravity: 0.27

Concha labiata

Description
A concha species that thrives in atmospheres rich with carbon dioxide. The lip-like upper opening cracks apart to allow a vertical growth of spiky leaves and bright seeds to stretch upward.
Conditions of occurrence
- Planet with thin Carbon Dioxide atmosphere
- Maximum gravity: 0.27
- Mean temperature inferior to 190 K

Concha renibus

Description
A species of concha that relies on heat sources to survive. As the bisected growth increases in size. it sprouts a single stalk topped with an array of luminous fronds that facilitate metabolism.
Conditions of occurrence
- Planet with thin Carbon Dioxide or Water atmosphere
- Maximum gravity: 0.27
- For Carbon dioxide, mean temperature between 180 K and 195 K
