Weblings are spider-like predators found only in Dark Agon. They wait in their web for prey. The Webling and the web can be destroyed with a shot from the Light Beam. There is a similar, much more resilient creature also found in Dark Agon called Ing Webtraps.
- "Weblings spin a network of energized snare lines, then sit in the middle and wait for prey to get caught in it, much like a spider. A webling is incredibly durable, though it has the darkling weakness to light." — Logbook "Webling" (Metroid Prime 2: Echoes)
- "Obstacle composed of tensile biomaterial, energized by Dark Energy. The Light Beam will be able to disrupt and destroy this obstacle." —Logbook "Dark Webbing" (Metroid Prime 2: Echoes Bonus Disc)
