This is the astonishing moment a huge whale shark swam among boats in a harbour. <br /><br />The whale shark, estimated to be four-metres-long, was seen swimming closely to the coast at Bo Thonglang Bay in Prachuap Khiri Khan, southern Thailand on May 8. <br /><br />Local Kuntida Kongkaew was walking along the beach when she saw the wild whale shark swimming around the fishing boat dock in the afternoon.<br /><br />Kuntida, who filmed the creature from a harbour area, said that it was her first time to witness the big fish coming very close to the residential area.<br /><br />She said: ''I’ve seen whale sharks before but I’ve never seen it this close. I was very surprised that it didn’t disappear when more people came to watch him.''<br /><br />The harmless shark was seen swimming for about an hour before it slowly went back to the ocean in the Gulf of Thailand.<br /><br />The woman also said that there were many rare creatures living in the Bo Thonglang Bay but they often hide under the deep ocean.<br /><br />Kuntida added: ''The beach is very quiet here, so big and small fishes like to swim here to get away from the busy tourist beaches.<br /><br />''The appearance of the whale shark also shows that the ocean is healthy and the animals aren’t encountered by human beings.''
