Deep-sea oxygen minimum zones can form naturally due to ocean circulation patterns.
Certain deep-sea regions have lower dissolved oxygen concentrations compared to surface waters. Frilled sharks are adapted to function efficiently in these reduced-oxygen environments typical of bathyal depths.

Operating under both crushing pressure and limited oxygen availability compounds physiological stress. Yet the species maintains predatory function in conditions that would challenge many shallow-water fish.
Such dual adaptation underscores the extremity of its niche. The deep ocean combines environmental stressors that rarely coexist at the surface, and the frilled shark persists within them.
