Neritantan

The Neritantan (ネリタンタン) is a species that inhabits the vast cave system within the walls of the 3rd Layer of The Abyss and live in the roots of the plants that grow haphazardly within it.

Description
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. Presumably because of this, their meat is described as very delicious, which 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 unimpregnable wall.

They have a symbiotic relationship with the plants they live in: they eat the plants' fruits and spread the seeds in their feces.

Trivia

 * Neritantan overpopulate the 3rd Layer, because of mass breeding. There are other subspecies of Neritantan in the other layers.undefined
 * The interiors of the hollow plant roots where the Neritantan live commonly contain leaves, flowers, and even fruits.
 * Their long fur is often used as a blanket.
