Not every one of us pays much attention to the number of sea jellies that are frequenting the beach sides. But there is a dedicated day that celebrates their very existence. World Jellyfish Day is marked every year on November 3, to recognise these slimy marine creatures which have existing since more than a million years. There is no particular event or observation as such but it is supposedly introduced by a group of marine biologists. Jellyfish are actually strange creatures, one of the major fact being they are not a fish, despite having it in their name.
