Here, to evaluate ontogenic changes in visual sensitivity in juvenile longtooth grouperEpinephelus bruneus, we investigated opsin gene sequences and expression in larvae and juveniles. The longtooth grouper has 10 opsin genes:Rh1, fiveRh2genes (Rh2A1-1,Rh2A1-2,Rh2A2,g6738, andg6740),SWS1, twoSWS2genes (SWS2A1andSWS2A2), andLWS. To date, five or sixRh2opsin genes have been reported in perciform fishes. Differential opsin gene expression was examined by RT-PCR; the results suggested that switching fromSWS1toSWS2occurs during early development, and that there is an absence ofLWSexpression between 14 and 40 days post-hatch. These ontogenetic changes in opsin gene expression may correspond to different requirements at different life stages.
