The box jellyfish has surprisingly stereotypic set of 24 eyes with each rhopalium carrying 6 eyes of four different types. Although the jellyfish eyes do not form images the way our eyes do but they are highly sensitive to light and are equipped with cornea, lenses, and retinas.
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.
The box jellyfish (Tripedalia cystophora) is far from a simple blob with tentacles. It’s an active, manoeuvrable predator, and it finds its way around with no fewer than 24 eyes.
The skyward gaze of one set of eyes belonging to box jellyfish provides evidence that these creatures -- which lack a conventional brain -- are capable of sophisticated behavior.
Box jellyfish have two different camera-type eyes, the upper lens-eye (ULE) and lower lens-eye (LLE), as well as two pairs of pigment pit eyes (not in the sagittal plane).
Box jellyfish may seem like rather simple creatures, but in fact their visual system is anything but. They've got no fewer than 24 eyes of four different kinds. Now, researchers have evidence...
Like other jellies, box jellyfish have no brain, perceiving the world only through their nervous systems. Most jellyfish catch their prey without having either brains or eyes, just by floating transparently through the sea until prey run into their tentacles.
Box jellyfish have a total of 24 eyes, categorized into four distinct types. Each side of their box-shaped body contains a cluster of six eyes, known as a rhopalium. Their eyes include structures analogous to human eyes, such as corneas, lenses, and retinas.
Cubozoans, or box jellyfish, each have twenty-four eyes of four types, but no central brain for information processing. An investigation of these eyes reveals optics as sophisticated as in ...
Box jellyfish are best known as near-invisible marine killers and a scourge of tropical holidaymakers, but it seems they should also be known for their oddball eyes. Zoologists have...
