Like the Reaper Vine, it will swing wildly at anything that comes near it, Samus included. It is much larger than its terrestrial counterpart, and it lacks its cousin's eye; instead, every part of its arm is vulnerable. It is encountered in the Gravity Chamber of the Phendrana Drifts and multiple rooms in the crashed Frigate Orpheon. These rooms are Reactor Core, Biohazard Containment, Cargo Freight Lift to Deck Gamma, Deck Beta Conduit Hall and Deck Beta Security Hall. In some areas, the Aqua Reaper can move along cracks in the ground. Like the Reaper Vine, it can be killed by a charged Plasma Beam shot.
