Uranaguapu

The Uranaguapu (ウラナグアプ) is a creature that makes its nest on the ceiling of the 6th Layer of the Abyss so they spend their time being upside-down.

Description
Uranaguapu were first documented in a note from the White Whistle Delver, Lyza "The Annihilator", being sold in Iruburu's Market of Value.

Uranaguapu are large badger-like four-legged beasts with upside-down heads. Their bodies are covered in black and white fur, their tails seem to grow six thin fingers and they have three hooked claws on each leg. They have four markings in between their eyes below their mouth, which displays four sharp fangs with molar teeth.

They possess a strange organ with a relic makeup near their heart that resembles a Your Worth.

Trivia

 * It is uncertain whether their ancestors had similar functions to relics or they introduced relics in their bodies and gained those functions.
 * It is stated in a note by Lyza that the Sicklehorn also possesses a strange organ near their heart similar to a Your Worth, like the Uranaguapu.
