Trunkarp

The trunkarp replaced its ancestor the ruskarp. As the bolagae evolved, it evolved along with it. It now has a prehensile trunk mouth in which it can grasp on to its food and bite off chunks. It developed a black and green stripe pattern to black in with all the black flora in the river. This also helps it absorb heat better in the icy waters. The main membranes still collect sunlight but the all 3 tentacle membranes too too. This is so it can still stay active even in the winter. They stay in swarms like their ancestors. The stripes confused predators when they try to pick out one in the swarm. They have suction cups on the tips of their main fins. This is used to hold on to rocks when feeding in strong river currents. The 2 ventral membrane fins are used to attract females. They will wave them around and stretch them out to try to look bigger than they are. Tunkarp only give birth to a single live young at a time.
