Neritantan

The Neritantan is a species that inhabits the vast cave system within the walls of the 3rd layer of the Abyss.

Description
Their flat bodies are shaped by their ribs which can deform and elongate as needed by exchanging air with their surroundings.

Their primary diet consists of Baracocha fruits and because of this, their meat is described as very delicious. 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 trees they live in: they eat the trees' fruits and spread the seeds in their feces.
