As the continent of Barlowe slowly split off from Darwin, the Sentrok population was split. As a result of competition, the Barlowe Tuitrok gained a larger body and a long neck in order to browse on higher plants. Its longer abdomen also grants it more developed digestive organs, to process more nutrients. It has thick pillar-like legs to support its heavier body, and a keen pair of posterior eyes to watch for predators. They have a heightened sense of fear compared to their ancestors, being very skittish when anything starts getting close. Additionally, they stay very still when they see movement, supplemented by their stripes which break up their silhouette. Despite all of this, they are still occasionally eaten by chkarshers and their close relatives, due to being ambushed from directly behind.
