AI Summary

Rob Shepherd, a roboticist, is developing a large underwater robot that can swim silently to avoid disturbing marine life. He drew inspiration from the oarfish, a fish that can reach several meters in length and propels itself with a ribbon‑like dorsal fin that moves in waves. To better understand the oarfish’s swimming mechanics, Shepherd consulted Willy Bemis, a retired ichthyologist from Cornell. Bemis’s expertise helped Shepherd translate the fish’s fin motion into design principles for the robot.
