The low-resolution visual system of box jellyfish is more derived than directional photoreception, and thus box jellyfish vision represents the most basic form of true vision in which multiple directional photoreceptors combine to create the first imaging and spatial resolution. This is different from the high-resolution vision that is observed ...
Craspedacusta sowerbii or peach blossom jellyfish [1] is a species of freshwater hydrozoan jellyfish, or hydromedusa cnidarian. Hydromedusan jellyfish differ from scyphozoan jellyfish because they have a muscular, shelf-like structure called a velum on the ventral surface, attached to the bell margin.
Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish [2] [3] found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of completely reverting to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual.
Lion's mane jellyfish swimming, side view. Human encounters with the jellyfish can cause temporary pain and localized redness. [18] In normal circumstances, however, and in healthy individuals, the stings of the jellyfish are not known to be fatal; vinegar can be used to deactivate the nematocysts.

Halitrephes maasi, commonly known as the firework jellyfish, is a species of deep-sea hydrozoan of the family Halicreatidae. Sightings have been reported at depths of 4,000 to 5,000 feet (1,200 to 1,500 m) near the Revillagigedo Archipelago off the Baja California Peninsula .
The S. gigantea tends to be more dominant in locations with a low productivity system, which in turn deters other predatory organisms, like fish, to high productivity systems (coastal, upwelling zones). However, the jellyfish remains an important predator for the deep sea, often competing with squids and whales.
