Octoliar

The Octoliar (マガイマキ) is a creature featured in Made in Abyss: Binary Star Falling into Darkness.

Description
The Octoliar mainly lives inside holes along walls.

Its ecology and movements are similar to a spider’s, but its body and appearance are like an octopus.

It can't walk very fast, but can temporarily increase its speed by exhaling air.

Its body is colored similarly to its environment as a form of camouflage. This makes it difficult to be seen from far away. When danger approaches, it emits poisonous gas to protect itself. The gas lingers in the air, similar to ink from an octopus.
