World Reef Awareness Day 1 Jun 2025

"Life under the sea is better than anything they got up there," Sebastian the crab once told Ariel. But are we doing enough to protect that underwater world? On June 1, we celebrate World Reef Awareness Day, a time to recognise the beauty—and fragility—of coral reef ecosystems. One magnificent example is the New Caledonian barrier reef, which wraps around Grande Terre, New Caledonia"s largest island. At over 930 miles long, it"s one of the longest continuous barrier reefs in the world. Its vast 9,300-square-mile lagoon is home to over 2,300 fish species, endangered dugongs, green sea turtles and migrating humpback whales.
