Unknown Life Form 36 is an unknown Door-like species seen in Metroid Prime 3: Corruption. It appears in the Metroid Cavern room on Phaaze, blocking both parts. To destroy it, Samus has to shoot at any one of its five eyes when open, causing it to become irradiated and explode. Alternatively, Samus could use the Hyper Ball for a more effective kill.
