Chironex fleckeri is the largest of the cubozoans (collectively called box jellyfish), many of which may carry similarly toxic venom. Its bell usually reaches about 16 cm (6.3 in) in diameter but can grow up to 35 cm (14 in). [8] From each of the four corners of the bell trails a cluster of 15 tentacles. [4]
Each rhopalium carries six eyes of four morphological types (lower lens eye LLE, upper lens eye ULE, pit eye PE and slit eye SE) and a light sensitive neuropil (NP, red broken line). The eyes are responsible for the image formation in the animal and the light sensitive neuropil is thought to be involved in diurnal activity".
Tripedalia has an advanced eye structure making it an efficient hunter and navigator within mangrove habitats. [7] Box jellyfish have 24 eyes that are categorized into four morphological types. These four types are made up of two pigment cup eyes and two lens eyes that enhance the jellyfish’s ability to navigate their environment and detect ...
Pelagia noctiluca is a jellyfish in the family Pelagiidae and the only currently recognized species in the genus Pelagia.

Box jellyfish have complex visual systems. Each of the four rhopalia on the bell of Tripedalia cystophora consists of a group of six eyes of four morphological types. The uppermost and the lowest eye each contains a lens, and there are also a pair of slit eyes and a pair of pit eyes.
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. [13] Their eyes are set in clusters at the ends of sensory structures called rhopalia which are connected to their ring nerve. Each rhopalium contains two image-forming lens eyes.
