Jellyfish evaporate in the sun. They're 98% water!

When jellyfish are in the water, they can be a bit intimidating.Their tentacles can pack a painful electrical shock.

Once they wash up on shore, however, they are anything but intimidating.

It turns out that jellyfish are 98% water. Most are transparent and bell-shaped.

If they end up on the beach, they will most likely evaporate in a few hours and mostly disappear.

Jellyfish also don't have brains, bones or a heart. They do have rudimentary sensory nerves though.
