Head-tail

The Head-tail (コウベウツシ) is a creature featured in Made in Abyss: Binary Star Falling into Darkness.

Description
The head and tail of the Head-tail has similar shape and move in similar ways, making it difficult to tell them apart.

Delvers have been confused before being killed.

It has spiky scales which it shakes and rubs together. Its tail stores electricity inside, which it uses to shock targets. Its mouth is split into four parts, making its bite extremely dangerous.

Although barely any of it is edible, its meat is shockingly delicious.
