Unlike many tetrapods and elasmobranchs, eye-closing ability is absent in bony fishes, with the single-known exception of the family Tetraodontidae. We observed the eye-closing response of the tetraodontid fine-patterned puffer, Takifugu flavipterus, which provides the first detailed data on the kinematics and mechanism of this ability in this family. During eye-closing behavior, the skin around the eye converges toward the center of the iris. This is very different to the reversing uni-directional (e.g., upward then downward) movem
