The Glowfin Ray is a flat, cartilaginous predator native to the volcanic shallows of Ralar Bay on the Dark Side of VOI 700 D. It is named for the distinct bioluminescent streaks that run along the edges of its fins, which pulse in rhythmic patterns while hunting.

The Glowfin Ray is a top-tier predator in the geothermal ecosystem, known for ambushing prey from beneath sandy vent deposits and stunning targets with a sudden flash of light.
