Earlier this week an online video of a whale shark in Hong Kong went viral.
Unfortunately there is no specific protection for this species in Hong Kong, so experts are calling on the government to introduce laws to protect whale sharks which are infrequent visitors to Hong Kong waters in the summer months.
The footage was posted by a Lamma Island resident Robert Lockyer, who said the footage was sent to him by one of the fishermen who encountered the shark on Tuesday.
Lockyer said there had been another local sighting on May 22, but he believed it was a different shark at another location.
The fisherman who took the video did not wish for his identity or the location of the sighting to be known.
