Jellyfish can be some of the most annoying creatures in the ocean, but can you imagine one the size of a human being?
Scientists diving off the coast of Falmouth, England saw just that over the weekend. Lizzie Daly, a biologist and ambassador for the United Kingdom's Marine Conservation Society, estimates that the creature was nearly five feet long. She and her cameraman were able to swim with the jellyfish for close to an hour.
Daly adds that the fish isn't a threat to humans and has just a mild sting. (USA Today)
