Darklings Tentacles are a type of Ing similar to the Reaper Vines and Aqua Reapers found on Tallon IV. Whenever a creature approaches them, they will wave around rapidly in an attempt to hit them. Samus encounters Darkling Tentacles in many places on Dark Aether, being absent only in the Sky Temple. Darkling Tentacles are also one of the few Ing that Samus cannot destroy.
- "Some darklings can open dimensional portals at will. They use this ability to hunt for unwary prey, reaching out to snatch them with their tentacles. Once ensnared, the prey is dragged to its doom. The tentacles are resilient; pure light energy can disrupt them. Nothing can destroy them." — Logbook "Darkling Tentacle" (Metroid Prime 2: Echoes)
