Scientists delighted but puzzled by new, strikingly coloured, ‘emerald in a coal mine’ Anthias.
Fascinating deep-sea species discoveries, ecstatic octopuses, speedy sharks and a tribute to the late Jack Wattley, the ‘godfather of Discus’.
Researchers from the california academy of sciences, diving on the st Paul’s rocks, a deep-water reef 1,000 miles off the atlantic coast of Brazil, have discovered a brilliantly coloured new species of anthias.
The divers were 130m down when the small fish caught their eye – its neon pink and yellow body and green fins made it stand out “like an emerald in a coal mine”. further morphological investigation alongside DNA analysis confirmed the fish is indeed new to science, and has been named Tosanoides
aphrodite in honour of the Greek goddess of beauty and love. This is only the fourth Tosanoides species discovered, and the first to be found in the atlantic (the others live in the Pacific).
females are a solid reddish-orange – typical of many ‘twilight zone’ dwelling fish as red and blue light can’t penetrate to this depth, so it helps with camouflage.
however, the reason for the males’ ‘highlighter pen’ colouration is still being explored as it goes against this theory. The scientists are sequencing the fish’s vision genes to try to better understand the benefits of their extravagant colour scheme.
A stunning discovery.
