A man was injured when he was bitten by a shark while fishing off the coast of Co Cork yesterday evening.
The man, who is from Belfast, sustained a serious lower arm injury while deep-sea angling.
He was given immediate first aid by the crew of the angling boat he was on, before being transferred to the lifeboat where further casualty care was given on board.
Crosshaven RNLI volunteers were called to the scene at 6pm.
A RNLI spokesman added: "This was more of an angling accident than a shark attack, there was a bit of a struggle when pulling the shark on board.
"We're not trying to panic anyone."
The boat, Deora De, sailed towards Crosshaven from about eight miles offshore and met the Crosshaven lifeboat about four miles south of Roches Point.
The lifeboat was met at Crosshaven by an ambulance and the man was transported to Cork University Hospital.
Although blue sharks are the most common species of shark in Irish waters, they rarely bite humans.
They usually feed on small fish and squid, and can live for around 20 years.
Until 2013, the blue shark was implicated in only 13 biting incidents with humans, four of which ended fatally.
A spokesperson for Crosshaven RNLI said that it was the first incident of a shark bite that it had dealt with.
The spokesperson said: "This is the first incident of a shark bite that we've had to deal with, although the blue sharks are common.
"I'd like everyone to keep in mind that the shark was nowhere near angling or swimming water levels. The men involved were fishing for sharks when the bite happened as he was trying to de-hook the shark.
The spokesperson also said that the men on board the boat did everything correctly when the incident occurred.
"I'm completely confident he would be back on his way back to Belfast with no issues," he said.
