A powder blue tang (Acanthurus leucosternon) darts through Aldabra’s coral reefs, adding a flash of electric blue to the vibrant underwater world. These herbivorous fish play an important role in keeping the reef healthy by grazing on algae. Aldabra’s reefs provide essential habitat for countless reef fish species, supporting the atoll’s rich marine biodiversity. Photo by the wonderful @evileyelander
