What is a jellyfish? A jelly goo with a painful sting? Yes, but jellyfish are much more! They are dazzling creatures that come in all sorts of colors and patterns, shapes and sizes. The author, Michelle McKenzie, will try to stump you with fun facts as she shares the latest jellyfish research from scientists at the Monterey Bay Aquarium, and the aquarium's sister institution, the Monterey Bay Aquarium Research Institute. On the CD-ROM in the back of the book, we peer into the world of the jellyfish with video clips of jellyfish in action as well as a complete glossary. Download the jellyfish screensaver and check out the cool activities. You can even e-mail the scientists with your jellyfish questions!
