Ingclaws are giant Darklings that dwell in certain areas on Dark Aether. They root themselves to a wall, where they grow and entrench into the wall and spend their lives feeding on flotsam in the air.
Ingclaws look like giant barnacles with clawed mouths. Their shells are nigh-invulnerable, and nothing Samus wields can kill them. Ingclaws feed on the flotsam floating in Dark Aether's atmosphere, exhuming it as a toxic vapor that can damage the Varia Suit. Some Ingclaws are found asleep; such specimens do not spew toxic vapor. Often, a large enough group of Ingclaw can create a haze from the vapor they create.
