of visual cell in deep-sea fish larvae that challenges a century of knowledge about vertebrate visual systems.<\/p>\n<p>Dr Fabio Cortesi\u00a0from The University of Queensland\u2019s\u00a0School of the Environment\u00a0said the finding could lead to new camera technology and medical treatments.<\/p>\n<p>\u201cFor more than 150 years, textbooks have taught that vision in most vertebrates is made of cones and rods \u2013 cones which work in bright light and rods for dark situations,\u201d Dr Cortesi said.<\/p>\n<p>\u201cBut our study of deep-sea fish larvae revealed a new cell type \u2013 a photoreceptor that optimises vision in gloomy or twilight conditions.<\/p>\n<p>\u201cIt combines the molecular machinery and genes of cones with the shape and form of rods.<\/p>\n<p>\u201cThis hybrid cell has the best bits of both the bright light and dark light systems to be something new that&#8217;s really efficient for twilight vision.\u201d<\/p>\n<p>The research team, which also included Dr Lily Fogg and Dr Fanny de Busserolles, examined the retinas of fish larvae caught at depths between 20 and 200 metres in the Red Sea during a series of marine exploration voyages.<\/p>\n<p>\u201cIt was very tricky because the larvae are only half a centimetre long and their eyes are smaller than a millimetre,\u201d Dr Fogg said.<\/p>\n<p>\u201cWe know in adulthood some of these fish descend to live up to 1 kilometre below the surface where they optimise their vision to see in the dark.<\/p>\n<p>\u201cWe wanted to investigate how their early vision develops in half-light closer to the surface, where they feed and grow before descending into one of the dimmest and largest habitats on Earth.\u201d<\/p>\n<p>Dr Cortesi says the team hoped the discovery would serve as inspiration for several fields of applied science.<\/p>\n<p>\u201cThis finding is fascinating because it builds on the little we know about the deep sea, but there are also practical applications for this knowledge,\u201d he said.<\/p>\n<p>\u201cIn technology, creating sensors based on this unique cell structure could lead to more efficient cameras&#8230;<\/p>\n<p><a
