| Research Abstract |
Light-induced body color change, or background adaptation, in teleosts is regulated by retinal photoreceptor neurons. To identify the photoreceptor neurons, we established a real-time and quantitative monitoring system for body color changes of living larval zebrafish. We found that developing zebrafish exhibit a transition from the embryonic-type to the adult-type pattern of body color change. Selective ablation of retinal rod and cone photoreceptor cells did not affect the profile of larval body color change, suggesting that unidentified non-rod non-cone retinal neurons are responsible for this photoreaction.
