Some say they must know risk, but Nettle ( Chrysaora melanaster) Order Semaeostomeae Tan, Michael N Dawson of the University of California, Merced for identification +Tripedalia cystophora (Mangrove box jellyfish) Utriculus (Blue Bottle or Indo-Pacific Portuguese Man-of-War) Sowerbii/previously Trastadacusta sowerbryi (Freshwater +Other additions (Singapore Biodiversity Record, etc) Jellyfish friends: Sometimes, small fishes can be seen near huge jellyfishes and even Ribbon jellyfishes including near their stinging tentacles. This is why it is important to dispose of plasticīags and balloons properly. Because plastic bagsĪnd balloons look like jellyfish, sea turtles may eat them and eventuallyīecome ill and/or die. May remain alive to produce medusa forms again later on.Ĭreatures that eat jellyfish are sea turtles. These medusa swim off and develop intoĪdults that may eventually reproduce sexually. Eventually, the polyp may reproduce asexuallyīy budding off medusa forms. These polyps may reproduce asexuallyīy budding off more polyps. In some small jellyfish, these larvae eventually settle down and develop The polyp may bud off to form more polyps, and each polyp transforms Tiny cup breaks away to form a tiny jellyfish. Stage, the polyp changes form again, budding into several tiny bell-shapedīodies that are stacked on top of each other like stacked cups. It then changes form to become a polyp that In the first larval stage, the offspring looks likeĪ sausage and goes through a brief free-swimming stage. The reproductive organs are in the stomachĪnd eggs and sperm are released through the mouth. The food produced is shared with the jellyfish, which in return providesīelonging to Class Scyphozoa and Class Cubozoa have of separate gendersĪnd stay the same gender. The algae undergo photosynthesis to produce food from sunlight. Microscopic, single-celled algae (called zooxanthellae) inside itsīody. The Upsidedown jellyfishhas a farm in its arms - it harbours Plankton in mucus on the underside of their bell-shaped bodies.

Jellyfish can sting and some, very painfully. Play with jellyfish! Like other cnidarians, Stout, branched, or long and ribbon-like. Structures called oral arms (not tentacles). Tentacles on the edge of the bell, others lack these. The animal moves by contracting its bell. Like other cnidarians, the jellyfishĭoes not have an anus and wastes are eliminated through the same opening Theīody called the bell is jelly-like, transparent or semi-transparent. Is the dominant and most conspicuous form in the life cycle.įor the features that they lack: no head, no organs, no bones. In Class Scyphozoa and Class Cubozoa, the jellyfish form Siphonophora which is a colony and not a solitary animal like other These include members of theĬlass Scyphozoa Class Cubozoa (which includes the highly venomousīox jellies) Class Hydrozoa (which includes the highly venomous Portuguese-Man-of-War in the Order Other cnidarians only take the form of a jellyfish in their life cycleĪnd don't take on the stationary form. Many cnidarians undergo a life cycle in which they take a jellyfish-likeįorm (the medusa) in one stage, and a stationary sea anemone-like Jellyfish may belong to various groups within the Phylum Cnidaria. Name, they are not fish and are more closely related to sea anemones More unluckily, theyĪre sometimes stranded on the shore and look like sorry heaps of jelly.īut no matter where you see them, don't touch them! In the water, these elegant creatures are a delight Jelly are creatures of the open waters and are only sometimes encountered Seen? Almost everyone knows what a jellyfish looks like!
