Some ideas for Fermi Island:
- A desert-dwelling species of miniswarmer that hibernates throughout most of the year in a mucous-sac. Once the rains come, they awaken in the desert pools, whereupon they feast, mate, and reproduce. The young then must rapidly mature and bury themselves before the waters dry up.
- A polyfee-plague species that has begun to affect the thornbacks. Infesting cryobowls, they feed upon the larval thornbacks, not killing them but leaving them weak and undersized. They are transported between cryobowls by latching onto adult thornbacks as they come to reproduce.
- A supershroom species that forms a symbiotic relationship with flashcells or other photosynthesizing microbes. The supershroom gathers up nutrients and water for the 'algae', and the 'algae' produces excess sugars for the supershroom.
- Predatory cloudswarmer species.
- Armadillo-like thornback.
- Polar skimsnapper split that inhabits the island, hunting dartirs, vermees, and young thornbacks.
- Scavenging swift hookphlyer split that takes up a niche similar to vultures.
- Fiddler crab-like split of the fan bloister that lives on the beaches.
- Barnacle-like split of the mini pukai that infest the beaches.
