Morphological variation in the Weberian apparatus of Cypriniformes
Abstract Cypriniformes (which includes the minnows, carps, loaches, algae‐eaters, stone loaches, and suckers) is a morphologically diverse and incredibly speciose order of teleosts. It has been suggested that a number of evolutionary innovations, key to improved hearing and feeding, have played an i...
