Kriangkrai Wongchan, 35, a resident of Phang Nga’s Thai Mueang District, explained that he was leading five people on a chartered fishing trip to the area when the orcas presented themselves.
The party were about eight kilometres off Koh Tachai, outside the Similan Islands National Park, when the killer whales arrived.
The four killer whales, about three metres in length, kept swimming and diving around the boat, Mr Kriangkrai said.
Concerned for the killer whales’ safety, the group stopped fishing and Mr Kriangkrai moved the boat out of the area and returned to shore.
Wanting to share the experience, he posted a video of the killer whales’ antics on TikTok under the name “aofpna”. The video received more than 55,000 “hearts” accompanied by more than 900 comments. (See video here.)
