A huge crustacean has been found lurking 7km down in the waters off the coast of New Zealand. The creature - called a supergiant - is a type of amphipod, which are normally around 2-3cm long.
But these beasts, discovered in the Kermadec Trench, were more than 10 times bigger: the largest found measured in at 34cm.Alan Jamieson, from the University of Aberdeen's Oceanlab, said: "It's a bit like finding a foot-long cockroach." "I stopped and thought: 'What on Earth was that?' This amphipod was far bigger than I ever thought possible."
The strange animals were found using a large metal trap, which had been equipped with a camera, housed in sapphire glass to keep it safe from the high pressures of the deep sea. Seven specimens were caught in the trap and nine were captured on film by the team from the University of Aberdeen, in Scotland, and the National Institute of Water and Atmospheric Research (Niwa), in New Zealand.
The largest specimen brought back up to the ship measured 28cm in length, while the biggest spotted on camera was 34cm-long.
The name "supergiant" was first coined after large specimens were caught in the 1980s off the coast of Hawaii.They have been since being seen in the Antarctic, where they grew up to 10cm, but these are now dwarfed by this latest find.
Dr Ashley Rowden, from Niwa, said: "It just goes to show that the more you look, the more you find."For such a large and conspicuous animal to go unnoticed for so long is just testament to how little we know about life in New Zealand's most deep and unique habitat."Over the last few years, scientists have been surprised by the life that is found in ocean trenches.
These deep-sea spots were once thought to be barren; too dark, cold and with too much pressure for anything to survive.But researchers have found a wealth of life in the deepest of the deep. As well as swarms of amphipods, they have uncovered shrimp-like creatures called isopods and snailfish that live 7,700m down.

'Conspicuous animal'
Amphipods have been found living in large numbers at the very bottom of ocean trenches, deep, narrow valleys in the sea floor that can plunge down to nearly 11km. The creatures are small, but extremely active, and seem to thrive in this place where the pressure is one thousand times greater than at sea level.
