A bottlenose dolphin has "aggressively" pushed a man underwater off the County Cork coast, according to a report made to the Irish Whale and Dolphin Group.
The report stated that the dolphin attacked the man twice and "lashed out with its tail", during the incident off Sherkin Island about two weeks ago.
It prompted the IWDG to repeat warnings that swimmers should be extremely cautious if interacting with dolphins.
The dolphin, known as Clet, is a new visitor to Irish waters this year.
The adult bottlenose is believed to have originated in French waters, but has been sighted off the Cork coast throughout the summer.
The incident took place on 26 July and the IWDG's sightings log said: "We are aware of a report of an adult swimmer nearby in wetsuit and mask, from a yacht at anchor, being aggressively pushed underwater by the dolphin.
"They got a bit of a shock as a result."
After the latest sighting of Clet, the marine conservation group reminded the public that "bottlenose dolphins are not cute and cuddly".
"Do not confuse the shape of their jawline with a smile. They can and do cause serious injury to humans and have killed in the past," the IWDG said.
"So please, to those in west Cork who may find themselves in the company of this wonderful and wild mammal, enjoy it, but stay safe."
