Résumé
The deep-sea is the largest and one of the dimmest habitats on earth. In this extreme environment, every photon counts and may make the difference between life and death for its inhabitants. Two sources of light are present in the deep-sea; downwelling light, that becomes dimmer and spectrally narrower with increasing depth until completely disappearing at around 1000 m, and bioluminescence, the light emitted by animals themselves. Despite these relatively dark and inhospitable conditions, many teleost fish have made the deep-sea their home, relying heavily on vision to survive. Their visual systems have had to adapt, sometimes in astonishing and bizarre ways. This review examines some aspects of the visual system of deep-sea teleosts and highlights the exceptional diversity in both optical and retinal specialisations. We also reveal how widespread several of these adaptations are across the deep-sea teleost phylogeny. Finally, the significance of some recent findings as well as the surprising diversity in visual adaptations is discussed.
