Previously we have observed the lack of immunoreactivity of taurine in the rod outer segments from light-adapted fish, such as the ayu Plecoglossus altivelis and lefteye flounder Paralichthys olivaceus. This finding prompted us to investigate if there is a difference in the immunocytochemical localization of taurine in the rod outer segments between the dark- and light-adapted states. In the retinas of the glass eel Anguilla japonica and the young goldfish Carassius auratus, extremely intense immunostaining was found in the cone outer segments, rod inner segments, photoreceptor supranuclear region and outer plexiform layer. The rod outer segments were not immunostained in the light-adapted state, while they were intensely immunostained in the dark-adapted state. Consequently, it was suggested that the lack of immunoreactivity in the rod outer segment may depend on light stimulation. In addition, the conspicuous immunocytochemical localization of taurine was discussed with the possible functional roles for taurine in the fish retina.

D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D005432	Flounder	Common name for two families of FLATFISHES belonging to the order Pleuronectiformes: left-eye flounders (Bothidae) and right-eye flounders (Pleuronectidae). The latter is more commonly used in research.	Plaice,Platichthys,Pleuronectes,Pseudopleuronectes,Halibut,Pleuronectes platessa,Flounders

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
