A species of ‘snailfish’, which lives over 7km deep, has been photographed by an international team including scientists from New Zealand.
Properly named Notoliparis kermadecensis, the fish is the deepest-living of any in the Southern Hemisphere, and can only survive at the huge pressure found at such depths, limiting their habitats to oceanic trenches.

“Dr Ashley Rowden, of National Institute of Water and Atmospheric Research (Niwa), said the fish were strikingly similar to the deepest fish ever caught on film – another snailfish known as Pseudoliparis amblystomopsis – at 7700m in the Japan Trench in 2008.
“A specimen of the Kermadec fish has only been caught once, in 1952 by the Danish Galathea expedition, and in 2007 it was photographed at a shallower depth of 6900m.”
