Cloudbubble Cryoutine

The Cloudbubble Cryoutine is an unusual cryoutine typically found in the atmosphere. Rather than forming symbiosis with glass flora, it is primarily found in clouds and Cloudbubbles. It produces energy by breaking down water into hydrogen and oxygen and it shares some of that with its host, like its ancestor, but the main benefit it gives to the Cloudbubble is hydrogen. The Cloudbubble uses the hydrogen to fly, giving the Cloudbubble Cryoutine some sugar produced during photosynthesis in exchange. In its free-living state, the Cloudbubble Cryoutine moves through the air with its greatly elongated flagella.

When not inside its symbiote, the Cloudbubble Cryoutine is primarily found inside clouds, which are a vast source of water. It can survive being turned into rain or snow; when this happens, or when its cloud dissipates, it enters a dormant seed-like phase until the wind picks it up and it enters a cloud again. Its dormant phase is aeroplanktonic and returns to normal once it enters a cloud. It has also regained the ability to reproduce through binary fission, and will do so every 10–20 minutes. It no longer produces seeds at all, only shifting between the dormant seed-like phase and a normal cell as needed to survive.
