The Phenagouti splits from its ancestor, the Okagouti. This species evolved with longer legs and a longer body in order to achieve greater speed for migration. It developed a neck and its ears are smaller. Like its ancestor, it lost the shield that served to defend it from predators and for photosynthesis. It is less green in appearance compared to its ancestor.
It feeds on flora such as Pioneeroots, Snow Puffs, Snow Windbulbs and Marbleflora; and fallen fruit. Like as its ancestors the Phenagouti only gets a part of its energy with photosynthesis; primarily getting its energy from the food that it consumes,. This species live in herds and search for food. As in its ancestor, the female gives birth to many offspring. Its light-sensing in the snout enables it to detect predators and search for food.
