A Kenobite is an unused creature from Metroid Prime 2: Echoes, and is presumably the basis for the mechanical version seen in the final game.
"Morphology: Kenobite Wall-walking hunter-gatherer Wall-crawling telekinetic; uses its power to acccurately guide acidic projectiles at enemies. Vulnerable to concussive blasts. The Kenobite prowls tunnels and caverns, using telekinesis to keep itself attached to the walls and ceilings. In combat, it will fire acid-filled globes, guiding them telekinetically toward the target. The creature is quite strong, and can only be dislodged by concussive blasts. Dying Kenobites explode in a burst of acidic fluids, a last strike at their victorious foe."
