Title: Lion's mane jellyfish
Content:  Lion's mane jellyfish (Cyanea capillata) are named for their showy, trailing tentacles reminiscent of a lion's mane. They can vary greatly in size: although capable of attaining a bell diameter of over 2 m, those found in lower latitudes are much smaller than their far northern counterparts, with a bell about 50 cm in diameter. Juveniles are lighter orange or tan, very young lion's manes are occasionally colorless and adults are red and darken as they age. While most jellyfish such as Moon Jellyfish have a circular bell, the bell of the Lion's Mane is divided into eight lobes that resembles an eight-pointed star, each lobe contains about 70 to 150 tentacles, arranged in four fairly distinct rows. Along the bell margin is a balance organ at each of the

Content:  The lion's mane jellyfish (Cyanea capillata), also known as the giant jellyfish, arctic red jellyfish, or the hair jelly, is one of the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans. It is common in the English Channel, Irish Sea, North Sea, and in western Scandinavian waters south to Kattegat and Øresund. It may also drift into the southwestern part of the Baltic Sea (where it cannot breed due to the low salinity). Similar jellyfish – which may be the same species – are known to inhabit seas near Australia and New Zealand. The largest recorded specimen was measured off the coast of Massachusetts in 1870 and had a bell with a diameter of 7 ft and tentacles around 120 ft long. Lion's mane jellyfish have been observed below 42°N latitude for some time in the larger bays of the east coast of the United States. The lion's mane jellyfish uses its stinging tentacles to capture, pull in, and eat prey such as fish, zooplankton, sea creatures, and smaller jellyfish.

Content:  As coldwater species, these jellyfish cannot cope with warmer waters. The jellyfish are pelagic for most of their lives but tend to settle in shallow, sheltered bays toward the end of their one-year lifespan. In the open ocean, lion's mane jellyfish act as floating oases for certain species, such as shrimp, medusafish, butterfish, harvestfish, and juvenile prowfish, providing both a reliable source of food and protection from predators.

Content:  Lion's mane jellyfish remain mostly very near the surface, at no more than 20 m depth. Their slow pulsations weakly drive them forward, so they depend on ocean currents to travel great distances. The jellyfish are most often spotted during the late summer and autumn, when they have grown to a large size and the currents begin to sweep them to shore. Unlike most pelagic jellyfish, they are completely solitary and rarely travel in groups Like other jellyfish, lion's manes are capable of both sexual reproduction in the medusa stage and asexual reproduction in the polyp stage. Lion's mane jellyfish have four different stages in their year-long lifespan: a larval stage, a polyp stage, an ephyrae stage, and the medusa stage. The female jellyfish carries its fertilized eggs in its tentacle, where the eggs grow into larva. When the larva are old enough, the female deposits them on a hard surface, where the larva soon grow into polyps. The polyps begin to reproduce asexually, creating stacks of small creatures called ephyrae. The individual ephyrae break off the stacks, where they eventually grow into the medusa stage and become full-grown jellyfish.

Content:  The taxonomy of the Cyanea species is not fully agreed upon; some zoologists have suggested that all species within the genus should be treated as one. Two distinct taxa, however, occur together in at least the eastern North Atlantic, with the blue jellyfish (Cyanea lamarckii Péron & Lesueur, 1810) differing in color (blue, not red) and smaller size (10 - 20 cm diameter, rarely 35 cm). Populations in the western Pacific around Japan are sometimes distinguished as Cyanea nozakii, or as a subspecies, C. c. nozakii. In 2015, Russian researchers announced a possible sister species, Cyanea tzetlinii found in the White Sea, but this has not yet been recognized by other authoritative databases such as WoRMS or ITIS.

Content:  indentations between the lobes – the rhopalium – which helps the jellyfish orient itself. From the central mouth extend broad frilly oral arms with many stinging cells. Closer to its mouth, its total number of tentacles is around 1,200. The long, thin tentacles which emanate from the bell's subumbrella have been characterised as “extremely sticky”; they also have stinging cells. The tentacles of larger specimens may trail as long as 30 m or more, with the tentacles of the longest known specimen measured at 120 ft in length, although it has been suggested that this specimen may actually have belonged to a different Cyanea species. This unusual length – longer than a blue whale – has earned it the status of one of the longest known animals in the world.

Content:  allergies). But in cases when someone has been stung over large parts of their body by not just the longest tentacles but the entire jellyfish (including the inner tentacles, of which there are around 1,200 ), medical attention is recommended as systemic effects can be present. Although rare, in deep water, severe stings can also cause panic followed by drowning. On a July day in 2010, around 150 beachgoers were stung by the remains of a lion's mane jellyfish that had broken up into countless pieces in Wallis Sands State Beach, Rye, New Hampshire, in the United States. Considering the size of the species, it is possible that this incident was caused by a single specimen.
Title: Cyanea annaskala
Content:  Cyanea annaskala is in the scyphozoan class of the phylum Cnidaria. The scyphozoans are the true jellies. It is within the order Semaeostomeae. The Semaeostomeae are the flag mouth jellies. It is within the family Cyaneidae, which contain the better known species of the lion's mane jellyfish. The phylogeny of the Lion's mane jellyfish has long been debated since their discovery, and the Cyanea Annaskala has long been implicated in this difficulty. The high proportion of cosmopolitan species in pelagic individuals makes it extremely tedious to differentiate between closely related members. Because of limited study and challenging experimentation, not all of the Cyanea species from the North Atlantic are considered valid. Protein and medusae analysis from Michael N. Dawson
