The search for Fungie will resume this morning after the Dingle dolphin was reported missing six days ago.
Mallow search and Rescue used SONAR to scan the sea bed yesterday, with divers also joining the search for the missing dolphin.
Jimmy Flannery of Dingle Sea Safari and Dingle Dolphin Tours spoke to Newstalk Breakfast to offer an update on the search so far.
He said: "Unfortunately, there's still no sign of our beloved Fungie after an extensive search yesterday.
"It's totally out of character for [Fungie] - I'm doing this for the last 33 years, and in all that time he has never disappeared for this length of time.
"It's very, very worrying at this stage."
He noted there are a few unusual situations happening in the area at the moment that may have drawn Fungie away from his usual spot.
He explained: "There's a lot of activity with whales and dolphins, and they seem to be coming closer to where Fungie hangs out. We're hopeful a small pod has come in and enticed him.
"Hand on heart, I'm hoping he's just off on an adventure somewhere, and he's happy and safe.
"There was [once] an April Fool's Day report that he had gone to Valentia - I would give anything now for them to ring me in Valentia and tell me he's there. We just don't care as long as he's OK and he's safe."
