Yes we have sharks on Koh Tao! Big ones and little ones. Koh Tao, known for its diverse marine life, includes various species of sharks. Here are some interesting facts about the shark species you can see around Koh Tao, along with the dive sites where they are most likely to be encountered:
The Blacktip Reef Shark:
These sharks are characterized by their distinctive black-tipped fins, which give them their name. They are relatively small and usually measure around 5 to 6 feet in length. Blacktip reef sharks are commonly found in shallow, tropical waters, and they are known for their active and inquisitive behavior. You can often encounter blacktip reef sharks at the bays like Aow Leuk & Hin Wong which are shallow, rocky areas known for their vibrant coral reefs and diverse marine life, great for snorkeling though not really practical for scuba diving.
Grey Reef Shark:
Grey reef sharks are known for their sleek grey appearance and distinctive white spots on their dorsal fins. They are typically found around coral reefs and drop-offs in the open ocean. These sharks are known for their curious nature and may approach divers to investigate. Chumphon Pinnacle is a popular site to spot grey reef sharks. It features a pinnacle rising from the depths and is often visited by these sharks as well as other marine life.
Bull Shark:
Bull sharks are known for their aggressive behavior and can tolerate both saltwater and freshwater environments, allowing them to venture into rivers and estuaries. They have a robust build and are known for their stocky appearance. Bull sharks are considered to be among the most dangerous shark species due to their proximity to coastal areas where humans swim. Although less common, there have been occasional bull shark sightings around Koh Tao. However, the sightings are infrequent, and the species is more commonly found in deeper waters around Chumphon Pinnacle or Sail Rock.
Guitar Shark:
Guitar sharks have a unique flattened body resembling a guitar, with elongated snouts and large pectoral fins. They are generally bottom-dwellers, spending much of their time on the ocean floor. Guitar sharks use their long snouts to search for prey like crustaceans and small fish in the sand. I’ve only ever hear of an encounter with guitar sharks at Chumphon Pinnacle, especially the deeper sandy areas at the foot of the pinnacles.
Whale Shark:
Whale sharks are the largest fish species and are known for their massive size and distinctive checkerboard-like pattern of spots and stripes. Despite their enormous size, they are filter feeders, mainly consuming plankton and small fish. Whale sharks are known for their gentle nature and are often sought after by divers and snorkelers for close encounters. Southwest, Chumphon Pinnacle and Sail Rock are among the popular sites where you might have a chance to encounter these majestic creatures, especially during the plankton-rich seasons, though they are also frequently sighted at Green Rock, White Rock, and Shark Island.
Remember that while encounters with these sharks can be thrilling, it’s important to approach them with caution, respect their space, and adhere to responsible diving practices to ensure the safety of both the divers and the marine life.
