If the sting is still bothersome, remember the nettle was just drifting around the Bay eating oyster enemies. The lifespan is about a year, however, when seasonal heavy rains reduce the water’s salinity to about 7 ppt, the planocysts remain dormant for as long as two years, extending the life expectancy from the polyp stage. In Virginia waters these jellies first appear in May, and usually vanish around September, though some occasionally remain well into November. In the bay, the underside of oyster shells is a preferred location. Because it effects trophic interactions within the food chain and the distribution of nutrients, it is considered a keystone species. Subsequent research has shown that the nettles are actually protectors, not predators, of the oysters. Response of Chrysaora quinquecirrha medusae to low temperature. Atlantic Sea Nettle is close species to the Pacific sea nettle but smaller and less colourful. Four thick, long, lacy oral arms hang from the bell margin, which is scalloped into shallow lobe-like structures called lappets. Blooms of Chrysaora quinquecirrha negatively impact humans. When these gelatinous creatures die, their bodies collect on the underwater sediment and through decomposition contribute to the carbon cycle. an animal which has an organ capable of injecting a poisonous substance into a wound (for example, scorpions, jellyfish, and rattlesnakes).
