The Silkfang (Gokouge, ゴコウゲ) is a monster from Made in Abyss

It is a large insect that is occasionally seen within the 1st layer of the Abyss. It has a 10-meter dome-shaped territory, and puts its sticky feelers inside of it. They use it as a trap to catch their prey when they carelessly enter their territory.
