Rhizostoma pulmo, commonly known as the barrel jellyfish, the dustbin-lid jellyfish or the frilly-mouthed jellyfish, is a scyphomedusa in the family Rhizostomatidae. It is found in the northeast Atlantic, and in the Adriatic, Mediterranean Sea, Black Sea and Sea of Azov. It is also known from the southern Atlantic off the western South African coast and into False Bay.
It is common in the Irish Sea. It typically is up to 40 cm (16 in) in diameter, but can exceptionally reach 150 cm (59 in) or larger , making it the largest jellyfish in British waters (Cyanea capillata reaches an even larger size, but is generally smaller in Britain). On 13 July 2019, wildlife biologist Lizzie Daly dived off the coast of Cornwall in the United Kingdom, along with the underwater cinematographer Dan Abbott. The two divers shared their encounter with a human-sized barrel jellyfish, Rhizostoma pulmo. The species could typically grow up to one meter (3.2 feet) and weigh up to 25 kilograms (55 lbs). However, they are not larger than the lion's mane jellyfish.
