The swampilla has split off from its ancestor, the beach slider. There were plenty of plants to eat once the migratory beach sliders arrived. They adapted to swamp living. The manipulative tentacle's hand split into three fingers to grasp the plants and bring them to a serrated beak to cut it up. Since plants are so abundant, and there is no prey available, the swampillas abandoned the meat portion of their diet. Even though there are no predators, the parents must still keep an eye on their young.
