How Many Brains do Jellyfish Have?

Jellyfish have no brains, blood or bones — in fact, the average jellyfish is composed of 94-98% water. A jellyfish consists mostly of a bell-shaped body with tentacles and a mouth.

More facts about jellyfish:

  • A group of jellyfish is called either a bloom of jellyfish or a swarm of jellyfish.

  • Most jellyfish are carnivorous, feeding off of fish, fish eggs, plankton and smaller jellyfish. Although they do not have a stomach, jellyfish have a gastrovascular cavity that absorbs nutrients.

  • In many Asian cultures, jellyfish is served pickled, salted or dried. A processed jellyfish loses more than 90% of its weight in the processing.
