Tunas are high-performance pelagic fishes of considerable economic importance and with a suite of biological adaptations for high-speed locomotion. In contrast to our understanding of tuna body and muscle function, sensory systems of tuna are poorly understood. Here we present the discovery of a remarkable sensory lateral line canal within the bilateral tuna keels with tubules that extend to the upper and lower keel surfaces. Neuromast mechanoreceptor organs are found periodically along the canal lumen, enclosed within tubular ossifications that we interpret as modified lateral line scales.
