A manned submarine has for the first time dived more than 10 kilometres to the bottom of the deepest part of the South Pacific Ocean. This is the second-deepest point in the world, and located in the Tongan Trench.
When the Japanese scientists got to the bottom they found the extravagantly named supergiant hadal amphipod, alicella gigantean. This creature looks prawn-like and is about 20 cm in length.
Fish, shrimps and other organisms living near and in the seabed were sampled.
The deepest point of the ocean, the Challenger Deep in the Mariana Trench in the North Pacific, reaches a maximum depth of 10,911 meters.
