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
Nomura's jellyfish resource. The Japanese company Tango Jersey Dairy produces a vanilla and jellyfish ice cream using Nomura's jellyfish. Consuming echizen kurage is potentially dangerous if the toxic part is not thoroughly cleaned and cooked. One study sought to use the mucin of the Nomura’s jellyfish to treat joint disease such as osteoarthritis. Like many invasive species, such as the cane toad, a simple solution is to take the species and convert them into fertilizer. Another study aimed at using an aqueous menthol extract of dried medusa to inhibit the growth of weed seedlings when added to soil. Nomura's jellyfish The diameter
