Experts have advised against helping porbeagle sharks to avoid being bitten or injured.
It comes after 1.5m (5ft) shark, believed to be a porbeagle, appeared to be in distress on the shoreline near Aberystwyth Pier, and people tried to help.
A HM Coastguard crew and members of British Divers Marine Life Rescue (BDMLR) were sent to the scene on Friday afternoon to assist and advise the public.
Porbeagle sharks can grow up to 11ft (3.5m) long and are regular visitors to the UK coast, although are usually found in deeper water.
“Porbeagles are not naturally aggressive towards humans, though there are reports of people being bitten when trying to help them back to sea,” said BDMLR.
