Jellyfish most are nowhere near that large). They have a moderately painful, but rarely fatal, sting. The increasingly common giant Nomura's jellyfish, "Nemopilema nomurai", found in some, but not all years in the waters of Japan, Korea and China in summer and autumn is another candidate for "largest jellyfish", in terms of diameter and weight, since the largest Nomura's jellyfish in late autumn can reach in bell (body) diameter and about in weight, with average specimens frequently reaching in bell diameter and about in weight. The large bell mass of the giant Nomura's jellyfish can dwarf a diver and is nearly
Bazinga (jellyfish) Bazinga (jellyfish) Bazinga is a genus of rhizostome jellyfish with only one known species, Bazinga rieki, found off the central eastern coast of Australia. Marine biologists Lisa-Ann Gershwin and Peter Davie described the jellyfish in 2013, from the holotype, which was collected in shallow water in the Brunswick River in northern New South Wales at high tide. The specific epithet refers to Denis Riek, who photographed a specimen in northern New South Wales, leading to the discovery. "Bazinga rieki" could not be placed in any known family or suborder of rhizostome jellyfish, so a new family Bazingidae was erected; it
