New Record Set For Deepest Dwelling Fish
mpicpp tips news that oceanographers have discovered a creature that sets the record for the most deeply dwelling fish on Earth. It was found in the Mariana Trench, some 8,145 meters below the surface.
The 30-day voyage took place from the Schmidt Ocean Institute's research vessel, Falkor, and is the most comprehensive survey of world's deepest place ever undertaken. The Hadal Ecosystem Studies (Hades) team deployed unmanned landers more than 90 times to depths that ranged between 5,000m and 10,600m. They studied both steep walls of the undersea canyon. ... Dr. Jamieson said: "We think it is a snailfish, but it's so weird-looking; it's up in the air in terms of what it is. "It is unbelievably fragile, and when it swims, it looks like it has wet tissue paper floating behind it. And it has a weird snout — it looks like a cartoon dog snout."
this rock has nothing on it and is very dangerous and there's nothing left to explore we should be spending this money on space elevators to get off this rock and not to explore the oshunz!!! lol
Is that it is delicious, and even more so due to its rarity.
These fish still have a ways down to catch yelp.
as in, this was on mainstream two days ago.

I think one way to fish is to drop a grenade or TNT stick into a body of water. Then, at least some of the fish float to the surface.
Is it realistic to think we could explore life in the depths of the ocean by dropping depth charges and waiting to see what comes up?
A recent article in New Scientist (paywalled, I don't have an alternative) suggests that 8 km is about the limit for fish. The problem, apparently, is that the pressure distorts protein shapes, eventually preventing them from working properly. The tissue (particularly muscle) of deep-sea fishes contains trimethylamine oxide, which may protect against this problem, and the deeper you go, the more of it the fish have, but by about 8km they are saturated with it.
Invertebrates have been found deeper, so presumably they have a different mechanism.
"it's so weird-looking; it's up in the air in terms of what it is. It is unbelievably fragile, and... it looks like it has wet tissue paper floating behind it. And it has a weird snout — it looks like a cartoon dog snout."
Sounds an awful lot like someone I saw walking out of the women's restroom at WalMart once.
How long before the Japanese hunt down that fish and serve it as sushi?
That is, does it taste better with lemon or garlic?
12,125 PSI pressure at that depth. Surface pressure is 14.7 PSI.

2) Source for atmospheric pressure at earth's surface
It's totally dark down there. No light except the occasional bioluminescence. It's like an off-world environment. Makes me wonder where else life can exist.
There are fish that can survive swimming on molten sulphur. http://news.bbc.co.uk/2/hi/sci...
Beat that.

As already stated, we spend trifles on space. We spend even less on these undersea adventures that all but Tea Party psychos feel enriched by, if for no other reason than because we find new and unique life forms that give us keys to untangling cancers, aging, and diseases of every kind. What we DON'T need is a back-breaking military budget when there are alternatives, such as flooding the Internet with countermeasures against the very successful lures al Qaeda, the Taliban, ISIL and other malevolent jackasses use to suck in vulnerable nitwits that become suicide bombers, rapists and child killers. No one has yet begun to tell them: "what if they're wrong, and Allah does not gift you with dozens of virgins and pleasures for eternity? What if what they say does not agree with the Koran by any means? Are you willing to burn in eternal hell for the terrible, evil things they want you to do?" There are countless such things we can be telling them, assaulting their faulty logic, hammering home the illegitimacy of their doings. "Who are the real good guys, and bad guys? Who went to Malaysia after the tsunamis, and brought food and medicine to the millions of Muslims that were starving and bleeding? How much effort has the Taliban made to build hospitals and schools, rather than destroy them?" If we start driving electric vehicles rather than spending $450B a year on oil we buy from despotic OPEC countries, that's hundreds of billions of dollars we have to spend on hospitals, schools, roads, bridges... and SPACE. We can also encourage the super-wealthy among us to play higher, more challenging games as Musk, Gates, and others have done, such as using their resources to produce inexpensive medications and verify herbal remedies, if Eli Lilly, Pfizer and others are only interested in profit? -- Electric Bill
We try to think outside the box-- biological systems surviving at enormous depths, extreme temperatures, feeding on arsenic and old lace-- but what if life is even more extreme than our wildest imaginings: life forms whose atoms are stripped of electrons, nothing more than ionic creatures, surviving within suns, or deep within gaseous bodies such as Saturn, Jupiter... or even within black holes? We could never know what is in such places, it would seem.
