• Rodrigues is celebrated not only for its terrestrial biodiversity but also for its rich and diverse marine ecosystems. The surrounding waters are teeming with life, hosting coral reefs, numerous fish species, marine mammals, and a variety of invertebrates. The island boasts impressive biodiversity statistics: 493 fish species, 175 types of gastropods, 104 algae species, 109 bivalve species, 138 coral species, 74 echinoderm species, and 41 bryozoan species. These marine inhabitants play a crucial role in maintaining the ecological balance and supporting local communities. However, they face threats from habitat destruction, runoff, and erosion, which lead to nutrient-rich waters that foster harmful algal blooms, adversely affecting marine life.

• Recognizing the critical need to preserve this unique biodiversity, Rodrigues has established multiple conservation strategies. Marine protected areas (MPAs) around the island serve as sanctuaries where fishing and extraction are prohibited, fostering the recovery and flourishing of marine species. Alongside MPAs, educational programmes, awareness campaigns, and eco-tourism initiatives promote responsible marine practices and highlight the importance of conservation. These efforts are supported by the Rodrigues Island Government and international partners, aiming to safeguard these ecosystems for future generations.

Marine Fauna
Coral Reefs The coral reefs around Rodrigues are critical, providing essential habitats for countless marine organisms. These reefs feature a mix of hard corals, soft corals, and coral fans, forming complex structures that offer shelter, food, and breeding grounds. Known for their species diversity and vibrant colors, these reefs draw snorkelers, scuba divers, and researchers globally, contributing to the island’s appeal and biodiversity conservation.

Fish Species Rodrigues’s waters abound with a diverse array of fish, attracting anglers and underwater photographers alike. The area hosts both reef-associated and pelagic fish, including visually captivating species like butterflyfish, angelfish, parrotfish, and surgeonfish, as well as larger predators such as groupers, snappers, and barracudas. These fish not only enhance the visual splendor of the reefs but are integral to the ecological dynamics of the marine environment.
Marine Mammals and Sea Turtles The marine biodiversity of Rodrigues is enriched by the presence of various marine mammals, including the humpback whale, observable during their migratory passage from June to November. Spinner dolphins are also a common sight, often found in large, playful groups that enchant both tourists and residents. Green sea turtles and hawksbill turtles are often seen nesting on beaches or while snorkeling.
Invertebrates Rodrigues’s marine life also includes a wide range of invertebrates such as octopuses, lobsters, shrimps, crabs, sea stars, and colorful nudibranchs. Nudibranchs, with their varied shapes and hues, further enrich the island’s marine diversity.
