Giant River Poostalk

Within the isolated areas of Dingus' river systems, the river bed was starting to become a bit crowded with flora species and so any that could grower higher up would be able to get more light. This lead to a local species of Poostalk to become a giant of its kind, becoming the Giant River Poostalk. While it is nowhere near as massive as some aquatic species of poralps that live in the oceans, the Giant River Poostalk fills a relatively similar ecological niche but in miniature. The many branching lobes means a greater surface area to get more light, thus allowing them to grow much bigger than the other species of Poostalks they share the water with. Aside from their larger size, the Giant River Poostalk is very similar to other species of Poostalks, such as their cells having large brownish-green pigments for photosynthesis. The Giant Poostalk also is fully multicellular and reproduces by budding or fragmentation, another advantage of having a lot of lobes that can break off and become new individuals. Living in the waters of Dingus, a landmass full of radioactive species, means that the Giant River Poostalk evolved from a species of Poostalk that had developed a resistance to radiation and as such also retains this resistance. Since the waterways the Giant River Poostalk inhabits are devoid of predators when it first appears, it currently only uses its fast reproductive rates to gain a competitive edge over other flora that dwell in the Dingus river system. The Giant River Poostalk also only thrives in freshwater, and so does not do well in the brackish water that is typically found at Dingus Beach and is entirely absent in salt water habitats.
