Jellyfish or jellies are soft-bodied, free-swimming aquatic animals with a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate to acquire propulsion and locomotion. The tentacles may be utilized to capture prey or defend against predators by emitting toxins in a painful sting. 

Jellyfish are found in every ocean, from the surface to the deep sea. Jellyfish range from about one millimeter in bell height and diameter to nearly 2 metres (6.6 ft) in bell height and diameter; the tentacles and mouth parts usually extend beyond this bell dimension.
