As populations of Fan Narr (Nataresukus bonii) increased in number within zone 3, interspecific competition began to become a problem. As populations looked for areas where competition was less prominent, they began to wander into the river system of Zone 16. While competition was not exactly present for them here, they had to deal with the water being lacking in salt. To adapt to these new conditions, they speciated and became the River Narr.

To deal with fresh water resulting in them building up too much salt in their systems, the River Narr developed the habit of expelling freshwater through their gills, although youngsters cannot do this as well as the adults meaning they must be hatched at the mouth of the river where the water becomes brackish. In the mouth of the river and in the coastal ocean water near the river mouth, the youngsters spend the first 4 months of their lives filtering the water for microscopic organisms such as the eggs of L. parvipisces and E. freshaquatica. After several molts of their exoskeletons, the juveniles will begin heading upstream into Zone 16 where they then pupate for transitioning to their adult lives of being raptorial carnivores.

They use their mandibles to efficiently tear the flesh of any prey item they chase down, with they spot with their keen eyesight (as their eyes have become larger than their ancestors). To help avoid being spotted in the river by prey or predators that rely on eyesight, their bodies have become darker in color (specifically a body that is the color of mud while having patterns like stripes that are a dark brown).

Much like their ancestor, the River Narr retains the internal chitin exoskeleton that grows with their bodies. Since the exoskeleton and their internal skeleton being separated by enzymes, the River Narr do not fall victim to age-related problems and as such can live a long time if they don't die from other things like starvation and the like.

When it becomes time to breed(which is in May), the River Narr will head towards the mouth of the river, hunt down another muscal and then lay their eggs on them. This serves as the first meal for the young when they hatch. Unlike their ancestors, the young are left to themselves, as they do not have to worry about predation at the mouth of the river and thus parental care beyond providing the young a place to hatch is not necessary.
