Rhinoroot
The Rhinoroot split from its ancestor and moved inland via the watersheds. It lost its filter-feeding juvenile tendencies and relies entirely on photosynthesis. Its reproductive cycle is based around floods. Rainfall such as during the wet season prompts it to produce spores which are washed into the watershed to join with other spores. The juveniles develop and live unrooted until the next flood, when they settle on land and take root to continue the cycle. Despite its name, there is nothing special about its roots and it is named more for the watersheds it is found in. Like its ancestor, it is immobile in adulthood, as its thick cell wall restricts movement and its muscles atrophy at that stage; juveniles, however, can still swim to right themselves when flipped over.
