Deep Fish

These fish are Pseudoliparis amblystomopsis, as filmed at a depth of 7km (4.8 miles) in waters off Japan:

"We certainly thought, deep down, fish would be relatively inactive, saving energy as much as possible, and so on," Professor Priede told BBC News.

"But when you see the video, the fish are rushing around, feeding accurately, snapping at prey coming past."

Because the fish live in complete darkness, they use vibration receptors on their snouts to navigate the ocean depths and to locate food.

Professor Priede added: "Nobody has seen fish alive before at these depths - only pickled in museums - and by the time they come up from the depths they look in a pretty sorry state.
Well, yes, and humans presumably look in a pretty sorry state when they sink down to 7km, by which time they're long since dead. Must breakthrough nature photography be marred by such petty calumny?

Amazing. The BBC article has the video of the fish.
