UP TO 15 sightings of the poisonous Portuguese Man-of-War sea creature have been reported on beaches along the west coast.

The blue-tinged sea creature, which looks like a jellyfish but is actually a jumble of tiny organisms filled with toxins in order to catch its prey, have been spotted washed up on Keel Beach, Keem Beach, and Boat (or Bog) Dock in Co Mayo.

The Achill Island Coast Guard have released a safety warning and Mayo County Council have erected signs warning members of the public and frequent beach users of this new danger.

Local GPs have also been notified of the sighting.

Sightings have also been made by the public on Lahinch beach in Co Clare.

If you do spot the creature, members of the public are advised not to touch it, as their tentacles’ sting can be deadly when they’re dead or alive.

The result of coming into contact with the creature’s sting can range from a severe allergic reaction to death, depending on the level of exposure.

If you do come into contact with the creature, dial 112 immediately.
