Each sea nettle is either in a free-swimming stage or a polyp stage. Its sting rarely poses a serious danger (e.g. Clinical Features. Even though their stings are not known to be fatal, it can lead to temporary pain and redness in the area of contact. Distribution. This keeps unfired nematocysts from firing and adding to the discomfort.[3]. Chrysaora chesapeakei it turns out is a friend to one of the region’s most iconic seafood species, the Eastern oyster. The bay nettle is the most common jelly in Chesapeake Bay during summer, and can be present from May to October. Contact Us Sea nettles are also able to consume minnows, bay anchovy eggs, worms, and mosquito larvae. Its mouth is located at the center of one end of the body, which opens to a gastrovascular cavity that is used for digestion. Birsa also found that acetic acid appeared to cause more nematocyst discharge in relation to salt water for Chrysaora quinquecirrha (Sea nettle). The defense mechanisms of the sea nettle reduces the amount of natural predators. Unlike other jellies, comb jellies don't sting. The above photo is a sea nettle swimming in a canal in Cape The dark water gives it a ghostly appearance. Each sea nettle is either in a free-swimming stage or a polyp stage. The Atlantic sea nettle (Chrysaora quinquecirrha), also known as the East Coast sea nettle or US Atlantic sea nettle, is a species of jellyfish that inhabits the Atlantic coast of the United States. Because these organisms occur within a narrow range of temperature (78 to 86°F) and salinity (brackish waters of 10 to 16 parts per thousand), scientists have been able to develop an experimental real-time computer model that predicts the likelihood that sea nettles might be found in an area based on the appearance of water masses that meet these criteria. C. quinquecirrha the sea nettle, a jellyfish that can inflict moderate to severe stings. While the sting is not particularly harmful, it can cause moderate discomfort to any individual stung. Sea nettle predation decreased at low dissolved oxygen concentrations when prey had no escape response at any dissolved oxygen concentration (fish eggs), was little affected for the slower swimming of the two active prey tested (copepods), and, as in mesocosm experiments discussed earlier, increased for fish larvae that can frequently escape or avoid capture at high oxygen concentrations. Chrysaora quinquecirrha (known as the Atlantic sea nettle or East Coast sea nettle) is a species of jellyfish that inhabits Atlantic estuaries, such as the Chesapeake Bay.It is smaller than the Pacific sea nettle, and has more variable coloration, but is typically pale, pinkish or yellowish, often with radiating more deeply-colored stripes on the exumbrella, especially near the margin. Virginia Institute of Marine Science The most common jellyfish in the summertime Bay, and the one most responsible for stinging swimmers, is the sea nettle Chrysaora quinquecirrha (Cry'-sore-ah kwin-kah-sehr'-ah). It has tentacles that surround the mouth to capture food. Sea nettles immobilize and obtain their prey using their stinging tentacles. sharp sting, but most reports indicate that the pain subsides after an hour or so. There are millions of stings each year but no fatalities. The medusae of C. quinquecirrha measures up to 40 cm (16 in) in diameter. It has long tentacles and a potent sting. Note the white color and absence of red markings typical of sea nettles from lower Chesapeake Bay. [1][2] Most recently, C. chesapeakei of estuaries on the Atlantic coast of the United States, as well as the Gulf of Mexico, was only fully recognized as separate from C. quinquecirrha in 2017. If vinegar is not available, the sting site can be washed with ocean water. In the Chesapeake Bay, you’ll most likely come across moon jellyfish — peaceful, pretty, blobby things floating around. Scientific Name. Its mouth is located at the center of one end of the body, which opens to a gastrovascular cavity that is used for digestion. SEE ALSO: jellyfish. The medusae of C. quinquecirrha measures up to 40 cm (16 in) in diameter. [1] The sea nettle is radially symmetrical, marine, and carnivorous. Image Credit: Corrine Hinton As of 2017, a distinct species, Chrysaora chesapeakei , another type of sea nettle that is also known as the bay nettle, has been distinguished from C. quinquecirrha . The sting can be effectively neutralized by misting vinegar over the affected area.
