About half of all vertebrates – those animals with a back bone – are fish with bony rays or spines. These 30,000 ray-finned fish species have evolved a similar feeding motion. As VOA's Rosanne Skirble reports, scientists have long hypothesized about the mechanics of that process, but now researchers at Brown University have x-ray video that shows it in action, in great detail.
