The localization of all 10 novel opsin transcripts in the adult zebrafish retina (sampled at ZT3) by RNA in situ hybridization, showing that each gene exhibits a discrete, partly overlapping expression profile. (RPE) Retinal pigment epithelium, (OS) outer segments, (IS) inner segments, (OPL) outer plexiform layer, (HC) horizontal cell layer, (BC) bipolar cell layer, (AC) amacrine cell layer, (IPL) inner plexiform layer, and (RGC) retinal ganglion cell layer.
