Their flat bodies are shaped by their flexible ribs which can deform and elongate as needed by inhaling air.
Their primary diet consists of Baracocha fruits and assumingly because of this, their meat is described as very delicious and makes them suitable for a wide range of dishes. To protect themselves from predators, they bunch up together in their nests and inflate their bodies, forming a near impregnable wall.
They have a symbiotic relationship with the plants they live in: they eat the plants' fruits and spread the seeds in their feces.
- The Neritantan overpopulate the 3rd layer because of mass breeding. There are other subspecies of Neritantan in the other layers.
- The interiors of the hollow plant roots where Neritantans live commonly contain leaves, flowers, and even fruits.
