ODDYSEUS_MISSION_AE#1744
Sample obtained from the Odysseus mission, sent to gather information about the planet Kepler-138d, a super-earth water world characteristic for its dense, water saturated atmosphere, and whose clouds occasionally appear green.

The mystery of these green clouds has finally been resolved with this analysis of samples that were collected from one of these green clouds as the rover descended into the atmosphere, 15km up in the clouds.

A diverse community of cyanobacteria-like phototrophic microbes (described as Ambrosiasphaera sp.) seems to be responsible for the unusual color of the clouds. These microbes, alongside the many others in the floating ecosystem they help support, seem to have developed hydrogen filled membranous organelles to float over the dense atmosphere. They also seem to have developed a cell wall with an unusual microstructure, extremely water absorbing to take advantage of floating droplets of water.

Some species seem to have developed predatory lifestyles, feeding on the plentiful Ambrosiasphaera chains, here seen one of these lifestyles, here seen one with one of the most unusual ways observed to catch and consume prey (described as Flagellovenator sp.). It floats passively with its flagellum extended, until it comes into contact with something. The appendix is covered in hairs not unlike those on the feet of Gekkonids, able to stick without any sticky substance needed. Once captured, it's bivalves cell wall opens and an amoeboid body penetrates the cell wall and starts digesting it's prey.
