People pay NT$2500 or more for the boat ride, just to snorkel swim with these giants at Exmouth, on the North West coast of Western Australia. Touching the shark is forbidden. Small aircraft are used to spot the sharks which then guide the dive boats to where one is.
Could the same technique be tried for Green Island?
Years ago whale sharks were known as The Tofu shark and many eaten in Taiwan. Today they are a protected species in Taiwan.
