So how does a jellyfish live without these vital organs? Jellyfish often look like a bell with tentacles all around the edge or hanging off the bottom. The shape of this bell is called a medusa because it looks like the evil Medusa in Greek mythology - a woman who had offended the goddess Athena who then changed her hair into snakes and made her face so hideous it turned people into stone. Medusa is also the word for jellyfish in many other languages including Greek, Hebrew and French. Imagine if you could just split in half and create a second version of yourself?
If you cut a jellyfish in half, the pieces of the jellyfish can regenerate and turn into two new jellies. Inmoonfish jellyfish travelled into outer space on the Space Shuttle Columbia so that scientists could examine how microgravity affected them. The jellyfish multiplied in space. When they came back to Earth, the scientists discovered that the space-born jellyfish couldn't figure out how to deal with gravity. Even though some jellyfish have very long tentacles, they never get tangled up or sting them.
It can have tentacles that are over 27 meters long - longer than the size of the blue whale which is the biggest mammal in the world! You might think that a gaggle of geese, a murder of crows, or a clowder of cats sounds interesting, but jellyfish groups have even better names. Toggle Menu. Explore Videos Games Tokyo Explore All.
