Abstract:

A combination of closely related light transmitting structures dorsal to the brain of tunas and other scombrid fishes is described as the “pineal apparatus.” Owing to the functional relationship apparently existing between this apparatus and the pineal area of the brain, and on the basis of the known correlation between light exposure of the pineal area and phototaxis in fishes, it is assumed, pending further confirmation, that the pineal apparatus may be a light receptor partially controlling phototactic movements.
