A huge crustacean has been found lurking 7km down in the waters off the coast of New Zealand. Amphipods have been found alive in large numbers at the very base of ocean trenches, deep, thinny valleys in the sea floor that can plunge down to nearly 11km. The creature called a supergiant is a type of amphipod, which are normally around 2-3cm long.
The creatures are small, but enormously active, and seem to thrive in this place where the pressure is one thousand times greater than at sea level. Alan Jamieson, from the University of Aberdeen's Ocean lab, said: It's a bit like finding a foot-long cockroach.
