A tourist spotted a "huge" shark swimming around a harbour during high tide.<br /><br />Olga Bates, 46, was visiting St Ives in Cornwall with family when they saw the large sea beast near boats.<br /><br />The group spotted the shark at 6:26am on Wednesday (March 23) during high tide.<br /><br />Experts say it was a basking shark - the second largest type behind the whale shark - that can grow up to 45ft.<br /><br />Olga from Knighton, Wales, said minutes before they saw a group of seals ''hiding'' from the shark.<br /><br />She said: "We had been very lucky.<br /><br />"We woke up so early to watch the sunrise and spotted seals hiding under the bridge and then we saw what they were hiding from - the shark.<br /><br />"It was amazing to see and it was so close to the beach. I was an amazing surprise for us, we have never seen one that close before.<br /><br />"We were enjoying the views and the sunshine, we were overwhelmed."<br /><br />Olga added: "It circled around the harbour a couple of times, we estimate it was around 10ft, it was longer than some of the boats.<br /><br />"We were down there for around an hour and a half until the water started to do down.<br /><br />"As soon as the water started to go down we knew it would be gone already. <br /><br />''It was amazing to see it so close, I was so lucky and my grandson was very excited."
