A “faceless” deep-sea fish not seen for more than a century has been rediscovered by scientists trawling the depths of a massive abyss off Australia’s east coast, along with “amazing” quantities of rubbish.
The 40cm fish was rediscovered 4km below sea level in waters south of Sydney by scientists from Museums Victoria and the Australian government’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) on the weekend.
Dr Tim O’Hara, the chief scientist and expedition leader, who is a senior curator of marine invertebrates at Museums Victoria, said it was the first time the fish had been seen in waters off Australia since 1873, when one was dredged up by a British ship near Papua New Guinea.
“This little fish looks amazing because the mouth is actually situated at the bottom of the animal so, when you look side-on, you can’t see any eyes, you can’t see any nose or gills or mouth,” O’Hara said via satellite phone from the research vessel Investigator on Wednesday. “It looks like two rear-ends on a fish, really.”
The Gippsland Lakes inAustralia is a beautiful example of bioluminescence. Noctiluca scintillans, commonly known as Sea Sparkle, is the non-parasitic, marine-dwelling dinoflagellate that exhibits the bioluminescence throughout its cytoplasm when disturbed.
