Cyanea capillata (Linnaeus, 1758)
-
This photo of the same individual as above shows the tentacles more contracted but the oral arms extended. Note the crab megalops larva riding on the outside of the bell.
-
In this view the bell is expanded, ready for another power stroke.
-
The margin is divided into 8 pairs of lobes, with deeper notches between pairs. This photo shows 3 sets of lobe pairs. The rhopalia are on small flaps between the 2 lobes of a pair.
-
The tentacles are in 8 U-shaped groups of 4 rows each, centered between the pairs of lobes. This view from under the bell basically shows that there is such a profusion of tentacles, oral arms, and gonads under the bell that it is hard to distinguish any discrete U-shaped groups!
-
The animal can flatten its bell out so that the lobes project to the sides, as seen in this individual floating near a jetty.

The lion's mane jellyfish (Cyanea capillata)
-
lion's mane jellyfish (Cyanea capillata) is the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans, seldom found farther south than 42N latitude. Similar jellyfish, which may be the same species, are known to inhabit seas near Australia and New Zealand. The largest recorded specimen found, washed up on the shore of Massachusetts Bay in 1870, had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and tentacles 36.5 m (120 feet) long.[1][2][3]
