On Shark Island dive site, Koh Tao, always raises the same question from first-timers, are there actually sharks? The answer is no, at least no more than anywhere else on Thailand’s diving island. The name comes purely from the shape of the rock above the surface, which from a distance resembles a dorsal fin cutting through the waves. Below the surface, however, the story is altogether more welcoming. An exceptional coral reef teeming with giant groupers, moray eels, blue-spotted rays, nudibranchs and angelfish. A site open to all levels, 40 minutes from Mae Haad.<\/p>\n

Shark Island dive site Koh Tao: behind the name<\/h2>\n

Shark Island takes its name from its profile above the water. Seen from a distance, this granite rock rising out of the sea off the south-east coast of Koh Tao looks remarkably like a shark’s dorsal fin. It is a striking optical illusion and a name that never fails to raise a smile once divers are underwater. Where the atmosphere is considerably more peaceful than the name suggests.<\/p>\n

Located 40 minutes by boat from Mae Haad pier, Shark Island is one of the most accessible all-levels sites on Thailand’s diving island. Its maximum depth of 18 metres, gentle to moderate current and exceptionally rich coral reef make it a welcome destination for Try Scuba beginners and experienced certified divers alike, particularly those with a passion for macro life and underwater photography.<\/p>\n

<\/p>\n

The coral reef at Shark Island \u2014 exceptional richness on Koh Tao<\/h2>\n

The defining strength of Shark Island is the density and diversity of its coral. Branching corals, massive corals and table corals succeed one another along the rocky walls, creating an extraordinarily rich habitat for reef life. Unlike some Koh Tao sites whose corals have suffered over the years. Shark Island maintains a reef in good health, colourful, alive and genuinely worth exploring slowly.<\/p>\n

Furthermore, this coastal reef is particularly photogenic: light filtering down from the surface illuminates the corals and creates ideal conditions for underwater photography. As a result, Shark Island has become one of Koh Tao’s favourite sites for divers pursuing the SSI Underwater Photography<\/em> specialty course.<\/p>\n

Marine life at Shark Island Koh Tao: what you’ll encounter<\/h2>\n
