Over 75 percent of deep-sea animals are estimated to possess some form of bioluminescence.
In the deep ocean, bioluminescent parasites and hitchhiking organisms sometimes attach to large pelagic fish, including oarfish. These parasites may emit faint light or reflect ambient bioluminescence from other organisms. On a creature already stretching over 10 meters, even small glowing attachments create an eerie visual effect. The oarfish’s smooth, silvery body provides surface area for temporary riders in a realm where light is scarce. Bioluminescence in the mesopelagic zone is often used for communication, camouflage, or predation. When combined with an elongated, ribbon-like host, the effect can appear almost supernatural. The deep sea layers spectacle on top of scale.

Imagine a serpentine fish longer than a bus drifting upright while faint points of light pulse along its body. In a world without sunlight, even tiny glows become dramatic. The deep ocean contains more bioluminescent organisms than any other ecosystem on Earth. That means giants like the oarfish move through constellations of living light. The juxtaposition of extreme size and pinpoint luminescence intensifies the alien impression. It looks engineered for myth.
Bioluminescent interactions reveal how layered deep-sea ecosystems truly are. Large vertebrates do not exist in isolation; they carry, attract, and influence smaller organisms. Studying these relationships helps scientists understand parasite-host dynamics under extreme pressure conditions. It also demonstrates how visual signaling persists even where sunlight never reaches. In total darkness, giants can still glow indirectly. The ocean manufactures its own stars.
