Faceless Fish Among New And Weird Deep Sea Finds
SYDNEY: Strange and wonderful creatures with no face and other fish, many new species were transported deep water off Australia on a scientific voyage that explores some parts of the unexplored ocean before.
The month-long trip off the east coast of the country has been investigating life that hides in a dark, cold chasm that plunges four kilometers (2.5 miles) below the surface using nets, sonar and cameras Of deep water.
The scientific chief on board “The Researcher” Tim O’Hara Museums Victoria to AFP on Wednesday that the search area was “the most unexplored environment on earth.”
Dice and crunchy red rock, inflated shells, blind spiders and deep eels were collected since scientists began their journey – Launceston North Tasmania towards the Coral Sea – May 15.
An unusual faceless fish was also collected, which has been recorded once before by the pioneering scientific team at HMS Challenger in Papua New Guinea in 1873.
“He does not have eyes or nose and mouth visible is down,” O’Hara said of the ship.
At such great depths, it is so dark that creatures often do not have eyes or produce their own light through bioluminescence, he added.
Another finding was that carnivores use silicon spiral fused sponges, glass efficacy. They get small crustaceans that cling to their velcro spines, slowly digesting there.
This technique differs from most offshore sponges, which feed on bacteria and other unicellular organisms filtered from passing currents.
“We have 27 scientists on board who are leaders in their fields and tell me that about a third of what we find are new species,” O’Hara said, with several thousand copies found to date and from two weeks to Go travelers.
Life at such depths is one of overwhelming pressure, there is no light, little food and subzero temperatures, with animals calling the home’s only means of survival.
As food is scarce, they are usually small and move slowly. Many are frozen and spend their lives afloat, while others have fierce thorns and fangs and wait until their food arrives.
Working in such an environment was difficult, O’Hara admitted each fishing, taking up to seven hours to deploy and retrieve the equipment and its eight kilometers of cable from the bottom of the sea, as it is so far.
However, the data collected has helped improve understanding of Australia’s high seas habitats, their biodiversity and ecological processes that support them, O’Hara said.
“This will help their conservation and management and help protect the impacts of climate change, pollution and other human activities,” he said.
