The oarfish’s spine is highly flexible, enabling undulating motion along its entire length.
Giant oarfish have a spine with numerous vertebrae, granting extreme flexibility. This allows undulating movements along the dorsal fin for propulsion and stabilization. Unlike large, rigid fish, the oarfish’s body can twist without injury, enabling vertical hovering and slow forward motion. The paradox of extreme length combined with delicate flexibility challenges human intuition. This adaptation allows the fish to maintain control, feed efficiently, and avoid damage in open water. The flexible spine is essential to surviving in deep midwater, where rapid escape or heavy armor is not feasible.

The spine’s flexibility reduces energy expenditure and provides mechanical advantage. Vertical positioning and fine-tuned undulations allow the oarfish to navigate efficiently in a low-food environment. The visual effect of twisting and bending along its massive length contributes to cognitive shock when observed, reinforcing the mythical perception of the species.
Studying spinal flexibility informs biomechanics, evolutionary biology, and robotics. The oarfish exemplifies how large vertebrates can maintain extreme length while avoiding mechanical failure. Its design allows survival and efficient movement without traditional structural reinforcement, a rarity among megafauna. The result is both functional and visually astonishing.
