A community portal about Jellyfish with blogs, videos, and photos. According to Wikipedia.org: Jellyfish are marine invertebrates belonging to the Scyphozoan class, and in turn the phylum Cnidaria. The body of an adult jellyfish is composed of a bell-shaped, jellylike substance enclosing its internal structure, from which the creature's tentacles suspend. Each tentacle is covered with stinging cells that can sting or kill other animals: most jellyfish use them to secure prey or as a defense mechanism. Others, such as Rhizostomae, do not have tentacles at all. To compensate for its lack of basic sensory organs and a brain, the jellyfish exploits its nervous system and rhopalia to perceive stimuli, such as light or odor, and orchestrate expedient responses. In its adult form, it is composed of 94–98% water and can be found in every ocean in the world.
With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life. Researchers have now unraveled the evolutionary relationships among the various species of box jellyfish, thereby providing insight into the...

Did you know jellyfish have been around for more than 650 million years, before dinosaurs roamed the Earth? But, what is a jellyfish? Is it really a fish? How many kinds of jellyfish are there? Which ones make their homes in our waters? Join Heather to find out the answers to these puzzling questions and afterward paint a tentacled, paper maché jellyfish of your own.
