Faceless Fish and 200 Years of Trash Found in World's First Survey of Deep Sea Abyss
The international crew on board The Investigator research vessel has pulled up some wonderfully bizarre specimens from a journey to the bottom of the sea, including a "faceless fish" that hasn't been seen since 1873.
The team, consisting of 40 scientists and support staff, are two weeks into a world's first exploration of the deep sea off Australia's western coast, in a mission called "Sampling the Abyss." The month-long expedition, led by Australia's Museums Victoria and the Commonwealth Scientific and Industrial Research Organization, aims to study abyss life at depths around 4,000 to 6,000 meters.
Chief scientist Tim O'Hara from Museums Victoria told AFP this area is "the most unexplored environment on earth."
"The data gathered on this trip will be crucial to understanding Australia's deep-sea habitats, their biodiversity and the ecological processes that sustain them," O'Hara said in a statement. "This will assist in its conservation and management and help to protect it from the impacts of climate change, pollution and other human activity."
So what kind of otherworldly creatures call the deepest parts of the ocean home?
Since the voyage began on May 15, the scientists have collected bright red spiky rock crabs, puffed-up coffinfish, blind sea spiders and deep sea eels, according to AFP.
"We've seen some awesome stuff," Di Bray from Museums Victoria told Australia's ABC News.
"On the video camera we saw a kind of chimaera that whizzed by—that's very, very rare in Australian waters," Bray continued. "We've seen a fish with photosensitive plates that sit on the top of its head, tripod fish that sit up on their fins and face into the current."
But Bray said the "highlight" was the faceless fish found off Jervis Bay at a depth of 4,000 meters.
"It's this fish with nostrils and a mouth and no face," she explained. "Apparently, it's got eyes way under the surface but really you can't see any eyes."
The last time this fish was caught was in the 1870s by the scientists onboard the HMS Challenger.
"So, it's not a new species, but it's still an incredibly exciting find, and we think ours is the largest one seen so far," a Blogging the Abyss post states. "Although very little is known about this strange fish without a face, it does have eyes—which are apparently visible well beneath the skin in smaller specimens. I doubt they'd be of much use though, so we've decided to call it the Faceless Cusk."
Blogging the Abyss: "It came from 4000 meters below the surface, where pressures are huge, the water is a mere 1⁰C, and the seafloor landscape is pretty barren!"John Pogonoski, CSIRO Australian National Fish Collection.
However, as SkyNews pointed out, there are plenty of other unusual specimens appearing at these depths.
"There's a lot of debris, even from the old steam ship days when coal was tossed over board," O'Hara said.
"We've seen PVC pipes and we've trawled up cans of paints," he continued. "It's quite amazing. We're in the middle of nowhere and still the sea floor has 200 years of rubbish on it."

- Research shows that 16 weeks of a vegan diet can boost the gut microbiome, helping with weight loss and overall health.
- A healthy microbiome is a diverse microbiome. A plant-based diet is the best way to achieve this.
- It isn't necessary to opt for a strictly vegan diet, but it's beneficial to limit meat intake.
New research shows that following a vegan diet for about 4 months can boost your gut microbiome. In turn, that can lead to improvements in body weight and blood sugar management.

Nearly 20 years have passed since the journalist Malcolm Gladwell popularized the term tipping point, in his best-selling book of the same name. The phrase denotes the moment that a certain idea, behavior, or practice catches on exponentially and gains widespread currency throughout a culture. Having transcended its roots in sociological theory, the tipping point is now part of our everyday vernacular. We use it in scientific contexts to describe, for instance, the climatological point of no return that we'll hit if we allow average global temperatures to rise more than 2 degrees Celsius above preindustrial levels. But we also use it to describe everything from resistance movements to the disenchantment of hockey fans when their team is on a losing streak.

On Aug. 18, Iceland held a funeral for the first glacier lost to climate change. The deceased party was Okjökull, a historic body of ice that covered 14.6 square miles (38 square kilometers) in the Icelandic Highlands at the turn of the 20th century. But its glory days are long gone. In 2014, having dwindled to less than 1/15 its former size, Okjökull lost its status as an official glacier.

I’m a Psychotherapist – Here’s What I’ve Learned From Listening to Children Talk About Climate Change

Eco-anxiety is likely to affect more and more people as the climate destabilizes. Already, studies have found that 45 percent of children suffer lasting depression after surviving extreme weather and natural disasters. Some of that emotional turmoil must stem from confusion — why aren't adults doing more to stop climate change?
