After most of the light hogging plants were gone, there was nothing stopping mancerxia amphaflorapod from returning to the sea. This time though, its leaves have evolved into large fins to propel it through the water. Its tentacles have degraded into mere steering devices. They now have developed gill-like organs that allow them to filter feed at the same time. These organisms reproduce in a manner similar to other plents, except they never leave the water.
