A tourist spotted a "huge" shark swimming around a harbour during high tide.
Olga Bates, 46, was visiting St Ives in Cornwall with family when they saw the large sea beast near boats.
The group spotted the shark at 6:26am on Wednesday (March 23) during high tide.
Experts say it was a basking shark - the second largest type behind the whale shark - that can grow up to 45ft.
