DID YOU KNOW?
Although the word is mentioned in their name, jellyfish are not fish. A group of jellyfish is called a 'bloom', 'swarm' or 'smack'. Large blooms can feature over 100000 jellyfish. Jellyfish don't have brains. Jellyfish use their tentacles to sting. Most are harmless to humans but stings from some species, such as the box jellyfish, can be very painful and sometimes kill.
