What is the longest jellyfish?

The longest (and thus, probably the largest) jellyfish is the Cyanea capillata, a “jelly” that has no skeleton and lives in the cold, northern ocean regions, such as the North Atlantic, Arctic, and North Pacific Oceans. Called the lion’s-mane jellyfish, it is one of the largest invertebrates and normally ranges in bell size (the jellyfish’s bulbous body) from about 5 to 6 feet (1.5–1.8 meters) across, with some reports of bell diameter as wide as 9 feet (2.7 meters). The tentacles add to their size, and some have been known to be up to 100 feet (30 meters) long.
