Jellyfish always much greater than the Lion's Mane, whose bell diameter can reach . The rarely encountered deep-sea jellyfish "Stygiomedusa gigantea" is another candidate for "largest jellyfish", with its thick, massive bell up to wide, and four thick, "strap-like" oral arms extending up to in length, very different from the typical fine, threadlike tentacles that rim the umbrella of more-typical-looking jellyfish, including the Lion's Mane. Jellyfish have a complex life cycle which includes both sexual and asexual phases, with the medusa being the sexual stage in most instances. Sperm fertilize eggs, which develop into larval planulae, become polyps, bud into ephyrae
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
