Box jellyfish box jellyfish's nervous system is more developed than that of many other jellyfish. They possess a nerve ring around the base of the bell that coordinates their pulsing movements, a feature found elsewhere only in the crown jellyfish. Whereas some other jellyfish have simple pigment-cup ocelli, box jellyfish are unique in the possession of true eyes, complete with retinas, corneas and lenses. Their eyes are set in clusters called rhopalia, located in pockets halfway up the outer, flat surfaces of the bell. Each contains two rhopalial ocelli with lenses, one directed upwards and the other downwards and inwards towards the
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
