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.
Giant phantom jellyfish live in every ocean except for the Arctic Ocean. However, because they typically swim deep below the surface, they are hardly seen by humans. Daniel M. Moore noted that one potential explanation is that the jellyfish swim higher up to expose themselves to ultraviolet radiation, which will rid them of parasites. Another ...
Jellyfish, also known as sea jellies, are the medusa-phase of certain gelatinous members of the subphylum Medusozoa, which is a major part of the phylum Cnidaria.
The organization's jellyfish collections have been the largest in the world, [aa] [ak] and its pioneering work with the animals resulted in a trend of jellyfish exhibitions in the United States. [al] [am] [48] In August 2016, aquarists cultured comb jellies for the first time in a laboratory, which may allow them to become a model organism. [49]
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 .
Cubozoa is a group commonly known as box jellyfish, that occur in tropical and warm temperate seas. They have cube-shaped, transparent medusae and are heavily-armed with venomous nematocysts. Cubozoans have planula larvae, which settle and develop into sessile polyps, which subsequently metamorphose into sexual medusae, [ 11 ] the oral end of ...
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.
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. [3] Scyphozoans have existed from the earliest Cambrian to the ...
