Before I read such an article, I don't have any idea of the size Jellyfish can reach. The AP photo here , one can easily sense what is a huge jellyfish, it dwarfs a diver. Now this kind of behemoths is plaguing Japan's fisheries. Every year on holidays, there are some people who are attacked by other jellyfish when swimming in the sea of the Penang's beachs. A little bit dangerous!
