Медуза зі щупальцями завдовжки з будинок? | A jellyfish with tentacles as long as a building?

The longest tentacles attributed to a lion’s mane jellyfish may reach about 36.5 metres—but this is an exceptional historical specimen, not a typical size. It was found in Massachusetts Bay in 1870; the measurement has been widely repeated, although the exact species identification has been questioned. Most individuals have much shorter tentacles.
