Displaying items by tag: lion's mane jellyfish
Dun Laoghaire-Rathdown County Council has put up warning signs in the lifeguarded area of Sandycove in south Dublin after sightings of lion’s mane jellyfish in the water.
Bathing has not been prohibited as it was with the water quality warning earlier this month.
As an added precaution the lifeguard warning flags are on red and will remain in place till further notice, the council says.
Lion’s mane jellyfish carry a painful and potentially lethal sting, even when washed up on the beach.
Last summer saw more than 150 lion's mane jellyfish recorded along the West Coast — amid a spate of incidents with swimmers being stung in Galway Bay.
But the East Coast was not immune, as a teenager was hospitalised after he was stung over most of his body off a Co Louth beach.
Swimmers in Galway were first put on alert in June after a number of people were hospitalised by stings from the dangerous marine animal.
Lion’s manes around the Irish coast this year are believed to be larger than usual to due warmers waters as well as an absence of their natural predators.
Meanwhile, the Irish Mirror has news of a ‘ghastly’ find on a Donegal beach in the shape of a partially eaten fish wholly visible inside a jellyfish.
The “savage” remains of what’s thought to be a moon jellyfish — and its final meal — were discovered by Belfast comedian Paddy Raff.

Herald.ie reports that 14-year-old Jack Dunne was stung over most of his body after getting entangled in the tentacles of a lion’s mane while swimming with friends off Port Beach, near Togher in Co Louth.
The teen needed “strong antihistamines and anti-inflammatory tablets” to recover from the intense pain of the jellyfish stings, which have the potential to cause death from anaphylactic shock.
Irish Water Safety chief John Leech warned that the dangerous marine species is not normally seen in the Irish Sea till autumn — and may be increased in number due to an absence of their natural predators, sunfish and turtles. Herald.ie has more on the story HERE.
Lion’s mane jellyfish currently being encountered in Irish waters are also larger than usual, according to one animal expert.
That’s according to zoologist Dr Tom Doyle, who spoke to The Irish Times after a recent spate of incidents that saw swimmers hospitalised by stings from the dangerous marine species in Galway Bay.
“It is not correct to say this is the first time they have been spotted on the west coast, as we had reports for the last two years, but they are particularly large and mature,” said Dr Doyle.
Lion’s mane jellyfish are more commonly seen in the Irish Sea, and reports of larger specimens similar to those off Galway and Clare have come in from North Wales and Liverpool.

#Dublin Bay junior sailors turned up to race yesterday on what was arguably one of the best sailing days of the season so far only to learn the first race of their September Series was scubbed due to 'jellyfish reasons'.
It's just the latest shut down of leisure pursuits in the capitals waters after Dun Laoghaire Rathdown County Council warned against bathing in 'Jelly fish infested waters' at nearby Sandycove.
As a finale to the 2014 season, racing was scheduled for six dinghy classes including the Optimist, Laser Radial and 4.7, Topper, Feva and 420 classes but not even the fact that over 100 junior sailors drawn from the four dun Laoghaire yacht clubs would be on the water rather than in it could stop yesterday's cancellation of the harbour races, such is the risk posed by the Lions mane jellyfish.
Last week Dun Laoghaire Harbour Master Simon Coate wrote to the yacht clubs and classes. ' A considerable number of Lions mane jellyfish have been sighted within the harbour. Please warn your members,' Captain Coate advised.
However, that may be just the tip of the iceberg in their numbers as the giant venomous species flocks to Ireland's warming coastal waters from elsewhere in the Irish Sea.
Meanwhile, restrictions on bathing have been lifted from nearby Sandycove Harbour and Killiney Beach after elevated bacterial levels were detected in the water earlier in the week.
Dollymount Strand's temporary bathing ban has also been lifted, as have a number of advisories in North Co Dublin.
However, precautionary notices remain at three locations – Burrow in Sutton, Claremont in Howth and Loughshinny Beach between Rush and Skerries – due to poor results of samples collected from outfalls at those locations.
Michael Viney writes in The Irish Times on growing concerns over lion's mane jellyfish and other harmful species in Irish waters.
The lion's mane is among the largest jellies found in Ireland and comes with a powerful sting, enough to disrupt "the stoical bliss normal to Dublin's Forty Foot bathing cove".
"Last year, the jellyfish was even more abundant in the Irish Sea than in 2009, and sightings from ferries found them from coast to coast," says Viney, who notes their and other jellies' dangerous effects on the marine industry and ocean ecosystems.
The decline of certain plankton-feeding species such as herring due to overfishing, coupled with a rise in sea temperature, has led to a marked increase of jellyfish of many different species in our waters such as the mauve stinger, which is blamed for decimating a Co Antrim fish farm's entire salmon stock.
