#Jellyfish - Swimmers have been warned away from Seapoint and Sandycove on the south shores of Dublin Bay after sightings of potentially dangerous lion’s mane jellyfish in the water.

Dun Laoghaire-Rathdown County Council has put up warning signs in the relevant areas to advise the public on the large jellyfish, whose stings from hundreds of tentacles can cause anaphylactic shock — even many days after they have beached.

#Jellyfish - Organisers of tomorrow's Ironman triathlon in Dublin Bay are currently monitoring the appearance of Lion's Mane jellyfish in the waters of the swimming course.

According to The Irish Times, the Ironman event is scheduled to begin early on Sunday 14 August with a 1.9km swim across the bay from Sandycove, which has been red-flagged since Wednesday after a number of the dangerous jellyfish washed up on the beach.

The Lion's Mane's powerful sting is known to cause anaphylactic shock, which is potentially fatal – and the sting is still potent even days after a jellyfish has died, as previously reported on Afloat.ie.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore. 

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.
