Pelagic fish spend almost all their time suspended in water, rarely interacting with the seafloor.
Oarfish live their entire adult lives suspended in the open midwater column, often hundreds of meters above the seafloor. Unlike benthic species, they require no substrate for feeding or shelter. Their ribbon-like body, continuous dorsal fin, and neutral buoyancy allow them to navigate this three-dimensional habitat with minimal effort. Remaining in midwater minimizes predation from benthic hunters while accessing dense layers of planktonic prey. Their lifestyle exemplifies extreme adaptation to open-ocean conditions. Survival depends entirely on suspension rather than hiding.

Imagine a 10-meter-long vertebrate drifting through water with no solid reference point. Humans rely on land for orientation; the oarfish uses currents, pressure, and the lateral line. The absence of bottom contact challenges intuition about what constitutes 'habitable' space. Scale and emptiness coexist. Their life is entirely fluid.
This midwater adaptation emphasizes how volume dominates deep-sea ecology. Giants like the oarfish are fully immersed in one of the largest ecosystems on Earth, largely invisible to humans. Their existence reveals the ocean’s vertical complexity. Even enormous creatures can be unseen for centuries. The open water becomes a stage for monumental survival.
