A team of Australian scientists in May 2017 discovered a faceless fish and other weird and wonderful creatures in the deep waters of Australia during their scientific journey to the parts of the ocean never explored before.
For starters, bright red spiky rock crabs, bioluminescent sea stars and sea spiders as big as dinner plates.
They also came across an unusual faceless fish, which has only been recorded once before by the pioneering scientific crew of HMS Challenger off Papua New Guinea in 1873.
The fish has eyes as well, but they're deep beneath the surface, and not visible, ABC reported.
The deep abyss off Australia's coasts is still mostly unknown to scientists.
"This little fish looks fantastic 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.
Now and again, marine researchers pull out a new fish species from the depths of oceans that looks out of this world.
"On the video camera we saw a kind of chimaera that whizzed by - that's very, very rare in Australian waters".
The AFP reports on the scientific bounty collected two weeks into a month-long expedition off the eastern side of Australia, where researchers are exploring the Commonwealth marine reserves from northern Tasmania to central Queensland.
While the Faceless Cusk was a great catch, O'Hara said it just one of many unique creatures the team expects to find during their voyage.
The "faceless fish" was found off Jervis Bay around 4,000 metres below the surface earlier this week, Diane Bray, an Australian scientist with Museums Victoria, said on Wednesday.
It doesn't have any eyes, you can't see it's nose and it's mouth is found underneath its body.
Data gathered from the survey will allow scientists to collect baseline data about the biodiversity of the area and would be helpful in measuring the impacts of climate change in the future.
"We know nothing about the abyss, and we need to know", said O'Hara.
"We've seen some awesome stuff".
The voyage will end June 16.
