Jellyfish have been found in every ocean, from the surface to the bottom, and even a few fresh water lakes.

They are made up of about 95% water and are one of the few types of animals that are symmetrical. They have no brain, no blood, and no nervous system.

Oh, and did i mention - They are fricken awesome?! Just look at them! wriggling away in the water all over the world!

Correction: They have a nervous cluster located in the bell. We can’t see it with the naked eye(of course), but they do have one. They can also somehow sense when they’re been snagged as seen here.
