If anyone was to mention diving in Thailand to you, then you would most likely think of one of the west coast destinations. Hardly a thought would be given to the small island of Koh Tao, which lies off the east coast in the Gulf of Thailand. I live and dive here, so I find this lack of attention a little unfair.
Freediving is easy. All you have to do, according to freediver extraordinaire, Stig Åvall Severinsen, is “learn to hold your breath as long as you can”. Simple.
The ability of two bottlenosed dolphins Tursiops truncatus to understand imperative sentences expressed in artificial languages were studied. One dolphin (Phoenix) was tutored in an acoustic language whose words were computer-generated sounds presented through an underwater speaker. The second dolphin (Akeakamai) was tutored in a visually-based language whose words were gestures of a trainer's arms and hands.
