In the south there has evolved a foxtrotter species that in many ways mirrors a counterpart found in the north despite having diverged from one another ten million years ago. In an example of convergent evolution both the Serinarctan tryenas and the Serinaustran watertrotter have specialized to catch fish in freshwater habitats, developing greatly elongated jaws with many hooked teeth, and even a small notch in the upper jaw to help hold slippery prey in place. Yet these adaptations arose in each group wholly independent of the other, and they are no closer related than either is to any other foxtrotter from the other hemisphere. Similar environmental conditions - namely, very wet, flooded landscapes - have produced some similar traits in both animals. But the differences are significant, too.
