Native to the Yangtze River valley in China, the Freshwater jellyfish, Craspedacusta sowerbii, prefers to live in still or slow-moving water bodies such as ponds, reservoirs, quarries, and lakes. Collected at Presa Rodrigo Gomerza and Rio San Juan repectively. Dumont (1994) speculated that C. sowerbyi may consume fish eggs, but Spadinger and Maier (1999) note that it is generally not considered an important predator of eggs or small fish. Polyps of Craspedacusta sowerbyi as predators on young striped bass. Taxon Information The distribution and ecology of the fresh- and brackish-water medusae of the world. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico. They can form three different types of buds: polyps, frustules, or medusa buds. Craspedacusta sowerbyi reproduce asexually in the polyp form, via budding. The polyp bud grows and develops while still attached to the original polyp. Unlike some other jellyfish, the nematocysts of freshwater jellyfish are unable to penetrate human skin (Peard 2000). Dodson, S.I., and S.D. Idaho Statesman. The United States did not report Craspedacusta sowerbyi until 1908. Ratte. Hydrobiologia 162(1):73-78.

Freshwater jellyfish have been observed in over 43 different water bodies in Indiana in locations that possess relatively high water quality. and across multiple seasons (or other periods hospitable to reproduction). 1992. 2010). Craspedacusta sowerbyi seems to favor calm water (Pennak 1989, Peard 2000). A critically endangered (CR) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as facing an extremely high risk of extinction in the wild. Information about Craspedacusta sowerbyi is incomplete. (Peard, 2000). 1999. that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle). Riquelme, D.Y. at http://www.serc.si.edu. Accessed With increased interstate and intercontinental travel, the translocation of Craspedacusta sowerbyi into new habitats continues (Davis 1998). Many studies of Craspedacusta sowerbyi feeding behavior have concluded that this species could have significant impacts on zooplankton communities due to increased predation pressure and prey preference (e.g., Smith and Alexander 2008, Stefani et al. Ohio Journal of Science 32:323-324. Adverse effects on fish populations due to C. sowerbyi-related food web alterations have yet to be documented. 2010. The ecology of Craspedacusta sowerbii Lankester, a fresh-water cnidarian, is a source of interest and confusion for many biologists. The diameter of the circular canal is anywhere from 5 to 22mm. Freshwater Biology 41:567-573. Therefore, freshwater jellyfish are unable to produce the painful sting caused by most marine jellyfish. Cooper. Indiana University of Pennsylvania, Indiana, PA. 25 pp. 127 pp. Because their size is relative small, and their body is transparent, these freshwater jellyfish go unnoticed and many still believe that there are no medusas that live in freshwater.

Lake Michigan Field Station, 1431 Beach St., Muskegon, MI 49441-1098 (231) 759-7824 It is believed that increased polyp feeding increases the energy stores of the frustules, allowing them to travel greater distances (Peard 2000). The ADW Team gratefully acknowledges their support. Craspedacusta sowerbyi is a freshwater jellyfish occupying all continents, . You likely were looking at freshwater jellyfish (Craspedacusta sowerbii), says DNR research scientist Gary Montz. Because C. sowerbyi populations are not checked by predation, freshwater jellyfish may be and have been abundant in ecosystems where fish abundance is also high, despite the potential for competition over food resources (Jankowski et al.

There is little or no evidence to support that Craspedacusta sowerbyi has significant socio-economic impacts in the Great Lakes. The medusa bud detaches to form a free-living adult medusa, which reproduces sexually via fertilized eggs, which develop into planula larva. Most populations are strictly male or female (Peard, 2000). A new record of Craspedacusta sowerbii, Lankester 1880 (Cnidaria, Limnomedusae) in Northern Italy. 1988. 2008. Belk, D., and D. Hotaling.

In this context, we present the first record of the freshwater jellyfish Craspedacusta sowerbii Lankester, 1880 in the Mediterranean island of Sicily, Italy. Payne, F. 1924. Trophic interactions of the freshwater jellyfish Craspedacusta sowerbii. However, in situ evidence of C. sowerbyi impacts on the zooplankton community or other trophic levels is currently lacking. It also contains the manubrium, four radial canals, and one circular canal, typical of most jellyfish. As of February 8, 2000, this organism was reported in 43 out of 50 states. Ecology and Classification of North American Freshwater Invertebrates. Table 1. living in sub-Saharan Africa (south of 30 degrees north) and Madagascar. 1956. In fact, there is a freshwater jellyfish, called Craspedacusta sowerbyi but it isn't very common. There are no known regulations for this species. breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female. (Johnson and Raven, 1999; Peard, 2000; Pennak, 1989). 2013. Brimleyana: The Journal of the North Carolina State Museum of Natural Sciences 25:35-42. Actually there are, because small freshwater jellyfish (Craspedacusta sowerbii) are native to Ohio as well as many other parts of the world. 1998. The bell margin is made up of statocysts while the velum is made of nematocysts, which are in abundance around the mouth. 1991. Jones. The location is not privately-owned or protected in any way. This organism shares many of the same traits characteristic of most jellyfish. Unlike their parasitic cousins in the flatworm group, turbellarians are tiny carnivores or detritus-eaters that glide smoothly across submerged leaves and other objects. Direct and indirect impacts of C. sowerbyi on fish populations are also unclear. Recently, the rare aquatic species spotted in Wuzhishan City has been confirmed as the peach blossom jellyfish (Craspedacusta sowerbii) by experts from Freshwater Fisheries Research Centre of Hainan Academy of Marine and Fishery Sciences. Topics It uses its nematocysts located on tentacles to sting and paralyze prey before scooping it into its mouth (Pennak, 1989). Pennak, R.W. 2000. American Midland Naturalist 78(1):155-166. Unlike some of the Turanchik. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. Although its stings can paralyze macroinvertebrates and small fish, its small nematocysts are not likely to penetrate human skin (Peard, 2002). Craspedacusta sowerbii Lankester, 1880 is considered the most widespread freshwater jellyfish species and has been reported in numerous locations on all continents except Antarctica. 2005). Invertebrate Zoologist, Bishop Museum, 1525 Bernice Street, Honolulu, Hawai'i 96817. Thus, populations are difficult to predict. The freshwater jellyfish is dimorphic, alternating between both a polyp and medusa morph (Johnson and Raven, 1999). The Regents Park medusa Craspedacusta sowerbyi and its identity with C. (Microhydra) ryderi. Craspedacusta sowerbyi populations are not checked by predation (Jankowski et al. This species has been detected in all continents except Antarctica (Dumont 1994). McCullough, J.D., M.F. The Animal Diversity Web is an educational resource written largely by and for college students. A European study used field enclosures and microcosms to test the potential effects of C. sowerbyi presence on the local ecosystem and found that there was a significant decrease in small crustaceans (especially juvenile cyclopoid copepods and B. longirostris) in microcosms with C. sowerbyi and a significant increase in chlorophyll concentration in enclosures with C. sowerbyi (Jankowski et al. This information is preliminary or provisional and is subject to revision. Science 91(2361):313-314. The mature medusa stage resembles a bell shape. Warm water temperatures and an abundance of food cause a proliferation of this species (Peard 2000). Potential: The impact of this widespread hydroid is unclear. Spadinger and Maier (1999) agreed with theorized effects on zooplankton communities, finding that C. sowerbyi hydromedusae prefer larger zooplankton (0.4–1.4 mm) and vigorous prey such as copepods. In: Ecology and Classification of North American Freshwater Invertebrates. The freshwater jellyfish, or Craspedacusta sowerbii, were discovered in the facility at Guilin University of Technology in South China's Guangxi Zhuang … The latter of these observations indicates that C. sowerbyi may be capable of contributing to trophic cascade effects.

And the identity of each organism was confirmed by taxonomists at KIZ. Jellyfish tend to lie on the bottom of shallow waters; they generally conserve their energy for efforts of capturing food or escaping predation (Pennak 1989). Living in Australia, New Zealand, Tasmania, New Guinea and associated islands. In a study of how C. sowerbyi predation could affect the traits of prey species, Jankowski (2004) found that C. sowerbyi predation did not appear to have a significant effect on the life history or development of Bosmina longirostris.
