Splitting from its ancestor, the floating gildron has simplified its ancestors form in order to conserve energy while at the same time increasing its rate of reproduction. Shrinking by nearly half its ancestors size, it is just visible to the naked eye. Floating close to the surface, it constantly photosynthesizes during the day. Intermingling with its cousins, it helps to form planktonic clouds miles in diameter. The spore-producer has become internalized, and now spores are released out of the spaces between segments.
