Sardinia’s marine waters are home to a wide array of fascinating marine species. From colorful fish to majestic sea turtles, you’ll encounter a diverse range of underwater inhabitants during your dives.

One notable species found in Sardinia is the Posidonia oceanica, a seagrass species that forms vast underwater meadows. These meadows are important breeding grounds for fish and provide shelter for many marine organisms. Exploring these seagrass meadows is like diving into a hidden world of vibrant colors and bustling marine life.

Other common sights include octopuses, moray eels, and various species of rays. If you’re lucky, you might even spot a seahorse or a nudibranch, those tiny and brightly colored sea slugs that are a favorite among underwater photographers.


One of the most captivating aspects of diving in Sardinia is the explosion of colors that greet you beneath the surface. The coral reefs are teeming with life and painted in a myriad of hues. As you descend into the depths, you’ll be surrounded by vibrant corals in shades of red, orange, purple, and blue. These hard and soft corals create a stunning backdrop for the countless reef fish that dart in and out of their hiding places.

The coral formations themselves are a work of art, with intricate patterns and textures that are a testament to the resilience of these underwater ecosystems. Take your time to appreciate the beauty of each coral species and the intricate symbiotic relationships they have with other marine organisms.


One of the highlights of living the sea in Sardinia is the chance to encounter dolphins in their natural habitat. These intelligent and social creatures are known to approach divers and interact with them in playful ways.

Sardinia is home to several dolphin species, including the common dolphin and the bottlenose dolphin. These friendly creatures often swim alongside boats, displaying their acrobatic skills and captivating onlookers with their playful behavior.

Diving with dolphins is a truly magical experience. As they gracefully glide through the water, their curiosity might lead them to approach you, creating a unique connection between humans and marine life. Just remember to respect their space and observe them from a distance, as they are wild animals and need their freedom.
