In the summertime in ocean waters, for example, off Ocean City, two types of large jellyfish often occur. The Moon Jelly (Aurelia aurita) is a clear, flattened disk, with numerous small tentacles around the edge, and a pink four-leaf clover design in the Jellyfish, common name for any of the invertebrate animals making up two classes of the cnidarian phylum. About 2700 hydrozoan and 200 scyphozoan species are known. The term jellyfish applies more specifically to the free-swimming, gelatinous organism cal After an number of questions on the chat-line about dangerous jellyfish and to build on Trevor Gardner's article in the last edition of the magazine, I thought Club members might like to know a bit more about these rather interesting animals. Most of us h We watched a young jellyfish (Aequorea victoria) swimming along just below the surface. Jellyfish are a kind of sea animal that drifts around in the water column, carried by wind, waves, and currents. They are related to coral and to sea anemones. This je Envenomation by the Irukandji jellyfish (Carukia barnesi) can result in an array of systemic symptoms known as Irukandji syndrome. In 1996, 62 people presented to Cairns emergency departments with Irukandji envenomation: 57 developed systemic symptoms, an The Irukandji (C. barnesi) is a small jellyfish approx 2cm diameter bell, responsible for an unusual and dramatic syndrome observed following stings in northern Australia, especially north Queensland. Stings have been recorded from Childers to Broome, and I am a scientist who works on the gelatinous zooplankton, especially jellyfishes and ctenophores. After a couple of decades of research and field experience, I am very concerned about recent changes in both the ocean and terrestrial ecosystems and what th They're slimy, oozy and flimsy. Misconceptions abound. They lead lives of mystery, even to scientists who devote years studying their secretive habits. Jellyfish and other gelatinous animals like comb jellies, pteropods and salps are actually among th Although many people mistake corals and anemones as plants, they are actually animals. They are part of an ancient and simple group of animals known as cnidaria. Jellyfish are also a member of this group. These animals are characterized by a symmetrical b The tropical Australian stinger research unit was founded in 2000 to allow joint research and ideas to be discussed and conducted between both medical and biological researchers on box jellyfish, or cubozoans. Historically, much of the research on cubozoa |
