Mauritius, a tropical paradise in the Indian Ocean, is not only famous for its white sandy beaches and crystal-clear waters but also for its diverse and vibrant marine life. The island's warm waters and extensive coral reefs make it a haven for snorkelers, divers, and marine enthusiasts eager to explore the incredible underwater world. From colorful reef fish to majestic sea turtles and rare marine species, Mauritius offers a mesmerizing encounter with sea creatures that captivate the heart of every ocean lover.

1. The Majestic Sea Turtles

One of the most beloved marine creatures in Mauritius is the sea turtle. These graceful swimmers are commonly spotted near coral reefs and lagoons. The two most common species found around Mauritius are:

  • Green Sea Turtle (Chelonia mydas) – Known for their herbivorous diet and large size, these turtles often inhabit the shallow seagrass beds.

  • Hawksbill Turtle (Eretmochelys imbricata) – Recognized by their striking patterned shells, they prefer coral reef environments and play a vital role in maintaining reef health.

Snorkeling and diving spots like Blue Bay Marine Park and Île aux Cerfs offer excellent chances to encounter these gentle giants.

2. Vibrant Coral Reefs and Reef Fish

Mauritius is surrounded by a rich coral reef ecosystem, home to thousands of marine species. The reefs provide shelter and food for an array of colorful reef fish, including:

  • Clownfish – Famous for their playful nature and symbiotic relationship with sea anemones.

  • Parrotfish – Essential to reef health, they help maintain coral growth by feeding on algae.

  • Butterflyfish and Angelfish – Recognizable by their striking colors and patterns, often seen swimming in pairs.

  • Lionfish – A visually stunning yet venomous predator with long, flowing spines.

Popular snorkeling and diving locations such as Flic en Flac, Trou aux Biches, and Belle Mare offer breathtaking views of these marine wonders.

3. Mysterious and Majestic Sharks

Sharks are among the most awe-inspiring creatures found in Mauritian waters. While most sharks here are harmless to humans, encountering them is a thrilling experience. Some of the most notable species include:

  • Blacktip Reef Shark – Frequently seen in lagoons and along coral reefs, they are curious but not aggressive.

  • Whitetip Reef Shark – Known for their sleek bodies and nocturnal nature.

  • Bull Shark – Found in deeper waters, often near shipwreck dive sites.

Divers can explore shark encounters at Cathedral Dive Site (Flic en Flac) and the Roche Zozo dive site near Blue Bay.

4. The Playful Dolphins and Whales

Mauritius is one of the best places to witness dolphins and whales in their natural habitat. Boat excursions from Tamarin Bay provide unforgettable dolphin-watching experiences, where visitors can see:

  • Bottlenose Dolphins – Known for their intelligence and friendly behavior, they often play alongside boats.

  • Spinner Dolphins – Famous for their acrobatic jumps and playful spins in the air.

From June to November, humpback whales migrate through Mauritian waters, making whale-watching tours an exciting opportunity to see these gentle giants up close.

5. Rare and Unique Marine Creatures

Mauritius is also home to rare and exotic sea creatures, adding to its underwater charm:

  • Mauritian Octopus – A highly intelligent and elusive creature, found in coral reefs and rocky crevices.

  • Leaf Scorpionfish – A fascinating and well-camouflaged predator blending seamlessly into the reef.

  • Moray Eels – Often spotted peeking from coral holes, they have a fearsome appearance but are generally harmless.

  • Marine protected areas like Blue Bay Marine Park.
