This food web needs some work. 1st off we need some maco sized detrivores. Then we need some herbovores to eat the currently uneaten Umbrellapuff and Sunstalk. Then we need some carnivores to eat the herbivores of those plus the River Chut and Snorkelcrest. Some scavengers might be good as well. Plus always more microbes are needed. One thing that bothers me is that we have a river yet only like 2 species swim in it and even then they are not that great of swimmers. Thus we need the niche of fish filled here.
