Thon Thamrongnawasawat, deputy dean of the Kasetsart University’s Fisheries Faculty, said in a Facebook post on Monday that an official report from the Department of Wildlife and Fishery says only 86 whale sharks were spotted in Thailand in 2020.
The professor said fewer than 100 whale sharks have been seen on average every year over the past five years, so seeing 280 of them swimming near Koh Tao is impossible.
He said whale shark usually swims back and forth, and are solitary animals. They may join a pod comprising four or five whale sharks, but then usually separate.
He added that the top five places in Thailand where a whale shark can be spotted are Richelieu Rock about 200 kilometres northwest of Phuket, Koh Tao’s Red Rock or Nangyuan Pinnacle, Eight Mile Rock off the coast of Koh Lipe, off the coast of Koh Tao and Chumphon province. Recently, whale sharks have also been spotted near Koh Losin and Phang Nga.
