The Notothenioid suborder of teleosts comprises a number of species that live below the sea ice of the Antarctic. The presence of 'antifreeze' glycoproteins in these fish as an adaptation to freezing temperature has been well documented but little is known about the adaptations of the visual system of these fish to a light environment in which both the quantity and spectral composition of downwelling sunlight has been reduced by passage through ice and snow. In this study, we show that the red… CONTINUE READING

A study of photoreceptor organisation in the retina of two species , the shallower dwelling Trematomus hansoni and the deeper dwelling Dissostichus mawsoni , identified a square mosaic in the former , and a row mosaic in the latter species ; the row mosaic in Dissostichus mawsoni with less tightly packed cone photoreceptors allows for a higher rod photoreceptor density .
SWS1 cones could not be identified by either microspectrophotometry or in situ hybridisation , presumably reflecting their low number and/or uneven distribution across the retina .
