This more derived group of nautstar lives in the tropical regions in and around the Vailnoff Ocean. They have a longer and more hydrodynamic shell, as well as longer arms. The eyes have moved upwards on the arms in order to get a wider view of its environment, to watch out for predators. Their arm lobes, while having less area to push water, are longer and more muscular. This allows the Horn Nautstar to glide in long bursts, achieving faster speeds than its ancestor. These arms can also be secondarily used to push in more microbes for them to eat. These many adaptations, combined with sheer numbers, have left the populations of ancestral nautstars more sparse in the tropical regions.
