GALLERY: The kelp forests of the Great Southern Reef

Science & Environment

The massive network of rocky reefs that lines much of southern Australia’s coastline is a shadowy cold-water underworld dominated by brown seaweeds known as kelp. The Great Southern Reef might not be as visually flamboyant as Australia’s world-famous Great Barrier Reef, with its colourful hard corals and sunlit shallow waters, but its communities of creatures are unlike anything else worldwide.
