oarfish

Researchers at Cornell University have designed a large underwater robot modelled on the oarfish, a deep-sea creature known for its long ribbon-like body and distinctive dorsal fin. The team studied how the fish propels itself with a rippling fin along its body and reproduced that movement in the robot, aiming for efficient, stable swimming at scale for future underwater exploration.

Engineers have designed a large underwater robot modelled on the oarfish, a deep-sea creature known for its long ribbon-like body and distinctive fin propulsion. The unusual anatomy of the fish, rarely seen alive, provides a template for efficient movement at depth. The project highlights how deep-sea biology continues to inform robotics, drawing attention from both science and technology audiences.

Scientists studying the oarfish, a rarely seen deep-sea fish, have found that its long, joystick-like pelvic fins may help it maneuver in the water. Researchers say the unusual fin design could inspire a new generation of underwater robots capable of precise movement at depth. The finding adds to growing interest in biomimicry for marine robotics.
