Figure: "Cubozoan visual system: The visual system of the cubozoan Tripedalia cystophora (A) comprises four sensory structures called rhopalia (B). 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).

Aequorea victoria, also sometimes called the crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America.. The species is best known as the source of aequorin (a photoprotein), and green fluorescent protein (GFP); two proteins involved in bioluminescence.
In 2011, Philips launched a microbial system for ambience lighting in the home. [ 90 ] [ 91 ] An iGEM team from Cambridge (England) has started to address the problem that luciferin is consumed in the light-producing reaction by developing a genetic biotechnology part that codes for a luciferin regenerating enzyme from the North American ...
Pelagia noctiluca is a jellyfish in the family Pelagiidae and the only currently recognized species in the genus Pelagia. [1] It is typically known in English as the mauve stinger, [3] [4] but other common names are purple-striped jelly (causing potential confusion with Chrysaora colorata), [5] purple stinger, purple people eater, [6] purple jellyfish, luminous jellyfish and night-light ...
The center is an NSF Gen-3 ERC formed in 2008, [3] and is a partnership between the lead university Rensselaer Polytechnic Institute, (RPI) two core partner universities—Boston University (BU) and the University of New Mexico (UNM)—and three other outreach universities—Howard University, Morgan State University (MSU), and the Rose-Hulman Institute of Technology (RHIT).
The medusae of hydrozoans are smaller than those of typical jellyfish, ranging from 0.5 to 6 cm (0.20 to 2.36 in) in diameter. Although most hydrozoans have a medusoid stage, this is not always free-living and in many species exists solely as a sexually reproducing bud on the surface of the hydroid colony.
The Scyphozoa are an exclusively marine class of the phylum Cnidaria, [2] referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word skyphos ( σκύφος ), denoting a kind of drinking cup and alluding to the cup shape of the organism.
