Utalue swamer replaces its ancestor the russian swarmer. It doubles its ancestors size. Its feeding way has changed, and instead of sucking micro-organisms from the ground, it swims with open mouth and the micro-organisms enter the mouth by themselves. Its mouth is bigger, because of that. It has developed primitive gills to breathe from, instead breathing through the skin. Still reproduces like its ancestor.
