Jellyfish are older than all of our ancient reptiles. Scientists believe they first swam in our oceans around 500 million years ago! There are more than 350 different species of jellies. At SEA LIFE Minnesota, you can see enchanting Moon Jellyfish and Atlantis Sea Nettles!
Jellyfish have no nerves; no blood, no heart and no brain, and their bodies consist 95% of water! Most jellyfish are harmless to humans, but a few including the Box Jellyfish can cause a painful sting. Some species of baby fish are able to hide amongst jellyfish tentacles for protection!
