Found several families of deep-sea fish that distinguish color

A new study by a team of marinologists from the University of Queensland in Australia shed light on some details of the evolution of fish and all vertebrate species in principle, including humans – because the new study focused on identifying some species of deep-sea fish, which, contrary to popular belief, are still can distinguish shades of color. It is worth noting that at such a depth – from 200 to 1,500 meters – the absolute majority of inhabitants possess monochrome vision and focus mainly on the blue spectrum of light, but the new research has indeed revealed some species of deep-sea fish, which amaze with their ability to distinguish a wide range of colors.

A team of specialists led by Dr. Fabio Cortesta conducted its research, analyzing the genome of more than 101 species of deep-sea fish living mainly at a depth of 1500 meters, found that there are at least 13 species of such fish that have a rather strong development of visual rods and cones – the main organs of distinguishing vision and color. Previous studies have shown that the deep-sea inhabitants mostly have only one squirrel on each sticks and a bump called opsins, however these thirteen species of fish have more than two such proteins in each of the visual organ.

Accordingly, this indicates that these fish in fact distinguish a rich gamut of color and light, which in turn may in the future shed light on many interesting features and details of the evolution of not only fish, but all vertebrates in whole, including person However, for now the team of specialists is in no hurry to share certain details of the research with the general public.

It is worth noting the fact that to a greater or lesser extent we are talking about the study of specific genomes and the characteristics of their development during the entire evolutionary period – so it can be assumed that in the very near future, experts will present additional results of their research on the correct analysis of evolution chordates.
