Unknown Life Form 17 is a phazon-based enemy encountered by Samus while on the Space Pirate Homeworld in the Defense System Chamber of Pirate Command. It blocks her path at one point, and is slightly plant-like. It has several large violet-colored phazon crystals growing out of it, as well as a eye-like structure. It can only be destroyed by overloading it with phazon.
