Most of the large, often colorful, and conspicuous jellyfish found in coastal waters throughout the world are Scyphozoa. [4] They typically range from 2 to 40 cm (1 to 15 + 1 ⁄ 2 in) in diameter, but the largest species, Cyanea capillata can reach 2 metres (6 ft 7 in) across. Scyphomedusae are found throughout the world's oceans, from the ...
The cannonball jellyfish (Stomolophus meleagris), also known as the cabbagehead jellyfish, is a species of jellyfish in the family Stomolophidae. Its common name derives from its similarity to a cannonball in shape and size. Its dome-shaped bell can reach 25 cm (10 in) in diameter. The rim is often colored with brown pigment.
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). [54] [55] They have a moderately painful, but rarely fatal, sting. [56]
The box jellyfish actively hunts its prey (small fish), rather than drifting as do true jellyfish. They are strong swimmers, capable of achieving speeds of up to 1.5 to 2 metres per second or about 4 knots (7.4 km/h; 4.6 mph). [19] and rapidly turning up to 180° in a few bell contractions. [4] Some species are capable of avoiding obstacles. [4]
The identification of sexually mature specimens, in both winter and summer, and at sites nearly 90 km apart, suggests a local population has been established. [ 1 ] [ 2 ] Reports of a new and previously unknown type of jellyfish near the southern Lebanese port of Sidon have also appeared in the Lebanese press, though these have yet to be ...

The largest recorded specimen was measured off the coast of Massachusetts in 1865 and had a bell with a diameter of 210 centimetres (7 feet) and tentacles around 36.6 m (120 ft) long. [2] 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 jellyfish measure about 8 inches (20 centimeters) in length. A rock slab shows one large (right) and one small (left) bell-shaped jellyfish with tentacles. The smaller animal is rotated 180 ...
