"Nigiri sushi is a type of Japanese dish made with sushi rice and fresh fish. The sushi rice is hand formed into a small clump, and the fish is sliced and pressed on top of it. In some cases, nigiri sushi uses a small strip of toasted seaweed called nori to bind the whole mixture together, although this is not obligatory. (wisegeek.com)"
