* Jellyfish have no right and left sides. They have a top and bottom like an umbrella.
* Some jellyfish have bioluminescent organs that emit light, which means they can glow in the dark.
* A jellyfish is also known as Medusa in Greek. A group of jellyfish is called a bloom, smack or swarm.
* Jellyfish do not have a respiratory system. Their skin is so thin that the entire body is oxygenated by diffusion. They are boneless, brainless and heartless.
* Even a dead jellyfish can sting.
