If you’re planning a diving trip to Phuket, get ready for more than just stunning coral reefs and crystal-clear waters—you’re about to enter a vibrant underwater world teeming with marine life. The Andaman Sea surrounding Phuket is home to some of the richest biodiversity in Southeast Asia, offering unforgettable encounters with creatures big and small.

Whether you’re a first-time diver or a seasoned pro, here’s a guide to some of the fascinating marine life you’re likely to encounter while diving in Phuket.

🐠 1. Colorful Reef Fish – The Heart of the Reef

As soon as you descend into the waters of Phuket, you’ll be greeted by a dazzling array of reef fish darting between corals. Some of the most commonly spotted species include:

  • Clownfish(yes, just like Nemo!)
  • Parrotfish
  • Butterflyfish
  • Angelfish
  • Damselfish
  • Lionfish

These fish form the colorful backdrop of nearly every dive and are especially abundant around Coral Island, Racha Yai, and the Khai Islands.

🐢 2. Sea Turtles – Gentle and Graceful

Spotting a sea turtle gliding effortlessly through the water is a magical moment for any diver. In Phuket, you’re most likely to see:

  • Green turtles
  • Hawksbill turtles

They are often seen feeding on seagrass beds or resting on coral shelves. Racha Yai and Ao Sane Beach are two hotspots for turtle sightings.

🐙 3. Cephalopods – Smart and Strange Creatures

Octopuses, squid, and cuttlefish are some of the most intelligent and captivating creatures you’ll meet underwater. Look out for:

  • Reef octopusescamouflaged in rock crevices
  • Pharaoh cuttlefishdisplaying hypnotic color changes
  • Squiddarting through the water in small groups

They’re usually more active during night dives or around rocky reefs.

🐬 4. Moray Eels – The Watchful Guardians of the Reef

With their snake-like bodies and toothy grins, moray eels may look intimidating, but they’re mostly shy creatures who prefer hiding in reef holes and caves.

You can spot:

  • White-eyed morays
  • Giant moray eels

They’re often found in Similan Islands and Phi Phi dive sites.

🐟 5. Barracudas – Sleek and Powerful

These fast swimmers are typically seen in large schools, and their reflective scales make them look like silver missiles slicing through the sea.

If you’re diving at Racha Noi or King Cruiser Wreck, you might even see a massive barracuda tornado—a stunning sight for photographers!

🐡 6. Pufferfish and Porcupinefish – Quirky and Adorable

Their round, expressive eyes and balloon-like defense mechanism make these fish favorites among divers. Watch them float calmly over coral gardens—and don’t worry, they only puff up when truly threatened!

🦈 7. Reef Sharks and Leopard Sharks – Harmless Hunters

Many divers are surprised to learn that sharks are commonly seen in Phuket—and they’re not dangerous. Reef and leopard sharks are shy and graceful creatures that usually mind their own business.

Top spots: Shark Point, Phi Phi Islands, and Hin Daeng

🐋 8. Whale Sharks – The Ultimate Encounter

While not guaranteed, whale sharks occasionally make appearances in Phuket’s offshore waters—especially at dive sites like Richelieu Rock, Koh Haa, and even around the Similan Islands during plankton blooms from February to May.

These gentle giants can grow up to 12 meters long and are the holy grail of diving experiences.

🦀 9. Macro Life – Tiny Creatures Worth the Zoom

For those who love the little things, Phuket has plenty of macro life to discover:

  • Nudibranchs(colorful sea slugs)
  • Shrimp and crabs
  • Seahorses
  • Pipefish

These tiny critters are often overlooked, but they make every dive a treasure hunt!
