We just learned about the very dangerous Sea Wasp jellyfish.
Another type of jelly is the Venus Girdle Jellyfish, also called the cestum veneris.
This is a very different kind of jellyfish because it looks like a big long clear ribbon with glowing white blue edges.
They can grow to be 1 meter (about 3 feet), and they usually live in the very warm waters of the ocean.
