The Lion’s Mane jellyfish

There have been a large number of confirmed sightings of the Lion’s Mane jellyfish in Carlingford Lough today.

A number of beaches in Ireland were closed earlier in the week due to the presence of the Lions Mane jellyfish. They are red in colour and have tentacles (stingers) that can grow up to three feet long.

The sting can be dangerous and cause serious symptoms including nausea, vomiting and respiratory distress. The pain from the sting is “excruciating” and some people can get anaphylactic shock in addition to sting pain. This can be fatal.

Carlingford Marina say they have contacted the Lough’s Agency, The Irish Coast Guard and Irish Water Safety regarding the matter and are waiting for further information.

They said: “For now, we urge everyone to be extra vigilant at sea, bathing, in the marina or even walking along the beach.”
