“”Use it don’t use it””…have Jelly Fish as a topic, there are so, so many different jellyfish. They appear to be so plain and simple but researching them and giving more info on this so called unfascinating life form will surely intrigue the listeners. “Jellyfish fact: Jellyfish has been around for more than 650 million years which means that they outdate both dinosaurs and sharks.” And that’s just one of many, see the site below. Happy researching!
