Sharks are rightfully called the ‘kings of the sea’, because in most marine food chains they are the top predator, and thus are a top-down control on the entire ecosystem. Sharks maintain the ecosystem balance and they play a big role in nutrient cycling and export from reefs.
The two most common species of sharks on Koh Tao are Whale Sharks and Black Tip Reef Sharks.
It is estimated that over 100 million sharks are killed by humans each year, and populations of most species of sharks are in sharp decline.
Contrary to popular belief, sharks are not dangerous to humans. According to local reports, only 3 shark attacks have occurred in the Gulf of Thailand in the last 100 years, and all were on fisherman, not divers of snorkelers. The chances of seeing a shark during the EMP are not high, but at many of the island’s deeper dive sites they can be found quite regularly (albeit less than a few years ago).
If you do see sharks, please report it on our reporting data base at www.marineconservationkohtao.com. Even if you do not see sharks, you can still report your dive information to SharkTrust.Org, because saying that you dived and didn’t see sharks is just as important as if you did. Also be sure to check out groups like Project Aware to find out how you can help to protect sharks.
