Jellyfish (Jellies) are known for being elegant and beautiful sea creatures, but don't be fooled by their graceful movements their long tentacles will sting you! Jellies were created with two major cell layers, the external epidermis, and the internal gastrodermis. They have no need for lungs, hearts, or many other standard organs found in most animals because nutrients and oxygen move freely through their bodies!
Though Jellis are carnivorous and will eat whatever they can get their tentacles on, most are not seriously dangerous to humans. Just because most are fairly harmless to people though doesn't mean they all are. Keep a keen eye out for these jellies: Sea Wasp Box Jellyfish, Irukandji Jellyfish, Portuguese Man O'War, Lion's Mane Jellyfish, and the Sea Nettle!
Watch these beautiful creatures swim blissfully through the water at the Monterey Bay Aquarium. Strange how something so dangerous can be so peaceful! You can also see other live video feeds by clicking the NEXT PAGE below the video.
