On average, An Atlantic Sea Nettle Jellyfish will live for 1 year in captivity, however with immaculate care and water quality, you can expect to see a lifespan of up to 2 years. Good water quality, on the other hand, will do much to help ensure good health. Four long oral arms hang down from the center of the cup and ring the mouth. Even so, captive bred specimens (which have recently become available to aquarium hobbyists) are preferable as they have a much higher record of survivability than those that are harvested from the wild. NANTUCKET — Bobbing and pulsating through the waves, a multitude of semitransparent, gelatinous and unwelcome visitors have populated the waters surrounding Nantucket for much of the summer.The Atlantic sea nettle jellyfish is responsible for stinging hundreds of beachgoers on both the north and south sides of the island over the past two months.Town lifeguards and dock staff have provided minor first aid for more than 200 jellyfish stings this season, more than double the number from summers past, Harbormaster Sheila Lucey said last week.Atlantic sea nettle stings produce a painful rash with peak intensity lasting up to 20 minutes. Particularly in the late summer months, it can often be found in very high abundance in brackish, estuarine environments.The adult form, known as a medusa, is most recognizable as a jellyfish.
The species is especially common along Western Atlantic coasts from New England to Brazil. At least three of the stings this year were severe enough to warrant a trip to the emergency room, but the vast majority were treated on the spot with hydrocortisone, Lucey said.“It’s evenly spread out across the island,” Lucey said when asked if there were more incidents on the north- or south-shore beaches.Emergency medical technicians on duty at the Aug. 24 Swim Across America fundraising event off Jetties Beach reported treating three stings, while swimmers said they saw relatively few jellyfish in the water compared with previous weeks, perhaps due to the wind direction and tide at the time of the swim.Maria Mitchell Association aquarium manager Jack Dubinsky said he first noticed a sharp increase in the number of Atlantic sea nettles last summer.Although the association has not been collecting formal data, he believes this year they arrived even earlier in the summer than last year.“That’s not surprising to me, because a lot of the biological activity is coming a little bit earlier just because we’re having an anomalously warm year,” he said. Living in the tropical and subtropical waters, these jellyfish prey upon a variety of smaller creatures, such as other jellyfish, ctenophores (comb jellies), zooplankton, and the occasional crustacean. Tentacles can be up to six feet long. Dean Geddes Dean Geddes I&M Staff Writer @DGeddesIM
