Koh Tao Marine Life
Koh Tao has some beautiful marine life that you would come to expect in the warm tropical waters of Thailand.
Koh Tao likes to pride itself on above-average numbers of whale shark visits throughout the year. This draws a lot of scuba divers to the island to try their luck in finding the holy grail of underwater marine creatures.
There is no set period where the whale sharks arrive however some say that the months between February and May they are most prevalent. 2019 was a particularly good year for whale shark sightings.
Whale sharks are slow-moving fish which makes they great for scuba divers especially those that like underwater photography. They are filter-feeding carpet shark so they are no danger to humans (as most sharks are anyway). They are the largest known extant fish species and it has been confirmed individual had a length of 18.8 m.
As with scuba divers, the whale shark prefers to be in warmer waters and is rarely found in water below 21 °C (70 °F). Thailand with its warm waters makes a great place for whale shark sighting. Even whale sharks like holidaying in Thailand. It has been estimated whale shark lifespans at 80–130 years. Whale sharks have very large mouths and are filter feeders. They feed almost exclusively on plankton and small fishes, and pose no threat to humans.
As Koh Tao translates to Turtle Island that would suggest that there is a number of turtles on the island. Koh Tao has two species of turtles, the Green Turtle and Hawksbill Turtle.
These turtles are most commonly found in the many protected bays around Koh Tao. Not only can they be seen by scuba divers but they are also regularly sighted by snorkellers.
In addition to the whale sharks they still have some excellent marine life. Notably big schools of barracuda, travelly, batfish (huge) and some of the biggest giant groupers that you would see anywhere in Thailand.
The usual reef fish are there such as fusiliers, butterflyfish, wrasse, angelfish, filefish and the very ugly scorpionfish.
