Just another reason to stay on dry land. Divers off the coast of England came face-to-face with an adult-human-size jelly fish. The encounter with the 5-foot long barrel jellyfish occurred last week off the coast of Cornwall. Barrel jellyfish normally reach 3-feet in length and pale in comparison to the lion's mane jellyfish - know to reach lengths of more than 120-feet, according to the Smithsonian Magazine. Do you have a fear of the ocean? Did this just send shivers down your spine? Have you experienced an interesting wild animal encounter?
