Thousands of jellyfish wash up on NI coastline | public advised not to touch them | ‘anaphylactic reactions are not uncommon’

A message on social media from the Portaferry Coastguard Rescue Team alerts the public to the jellyfish - and to their associated dangers.

“Look what has been washed up around the coast of Cloughey today.

“Hundreds maybe thousands of Lion’s Mane Jellyfish.

“Anyone finding a lion’s mane jellyfish washed up on the beach should also be aware that the tentacles of this species retain their potent sting long after the jellyfish has died, and dead specimens should therefore never be touched under any circumstances.

“If your dog comes into contact with a Lion’s Mane Jellyfish, immediate veterinary attention is advised as anaphylactic reactions are not uncommon”.

Lion’s manes are one of the world’s largest-known species of jellyfish, with long tentacles that can give a painful sting.

People should not attempt to return them to the sea, due to their sting, which can leave a painful rash even after the creatures are dead, he added,
