Did you know that manta rays swim so efficiently, that their biomechanics have inspired the development of the most energy-efficient soft robot? Developed at North Carolina State University, the robots are called ‘butterfly bots’, and can swim more than four times faster than previous swimming soft robots. So, whilst manta rays may appear to be moving slowly, with their effortless pectoral fin strokes, they are actually moving incredibly fast! 📸 @jasminecorbettphotography 📍Raa Atoll, Maldives
