Vision plays a major role in the life of most teleosts, and is assumingly well adapted to each species ecology and behaviour. Using a multidisciplinary approach, we scrutinised several aspects of the visual system and ecology of the Great Barrier Reef anemonefish,Amphiprion akindynos, including its orange with white patterning, retinal anatomy and molecular biology, its symbiosis with anemones and sequential hermaphroditism.Amphiprion akindynospossesses spectrally distinct visual pigments and opsins: one rod opsin, RH1 (498 nm), and five cone opsins, SWS1 (370 nm), SWS2B (408 nm), RH2B (498 nm), RH2A (520 nm), and LWS (554 nm). Cones were arranged in a regular mosaic with each single cone surrounded by four double cones. Double cones mainly expressedRH2B(53%) in one member andRH2A(46%) in the other, matching the prevailing light. Single cones expressedSWS1(89%), which may serve to detect zooplankton, conspecifics and the host anemone. Moreover, a segregated small fraction of single cones coexpressedSWS1withSWS2B(11%). This novel visual specialisation falls within the region of highest acuity and is suggested to increase the chromatic contrast ofAmphiprion akindynoscolour patterns, which might improve detection of conspecifics.
