The lion's mane jellyfish (Cyanea capillata) is one of the largest species. The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5 m (119 ft 9 in) long (though most are nowhere near that large).
The new species of jellyfish is considered “relatively large,” its body reaching just over 1 inch in height and its tentacles measuring over 2 inches in length, the study said.
Although the Scyphozoa were formerly considered to include the animals now referred to as the classes Cubozoa and Staurozoa, they now include just three extant orders (two of which are in Discomedusae, a subclass of Scyphozoa). [11] [12] About 200 extant species are recognized at present, but the true diversity is likely to be at least 400 ...
Burgessomedusa from the mid-Cambrian Burgess Shale is the oldest known free-living medusa (commonly known as jellyfish). [9] The affinities of the class Polypodiozoa, containing the single species Polypodium hydriforme, have long been unclear. This species is an endoparasite of fish eggs and has a peculiar life
The exceptionally well-preserved fossils are a remarkable find, given that the soft-bodied animals are made of 95% water. The jellyfish measure about 8 inches (20 centimeters) in length.
Staurozoa is a class of Medusozoa (or jellyfish).It has one extant order: Stauromedusae (stalked jellyfishes) with a total of 50 known species. A fossil group called Conulariida has been proposed as a second order, [3] although this is highly speculative.
Although unspecified species of box jellyfish have been called in newspapers "the world's most venomous creature" [40] and the deadliest creature in the sea, [41] only a few species in the class have been confirmed to be involved in human deaths; some species are not harmful to humans, possibly delivering a sting that is no more than painful.

A marine biologist got the surprise of her life when she swam off the southwestern coast of England and came across a jellyfish the size of a human.
