Great Barrier Reef, the world's largest coral reef system, stretches over 2,300 km off Australia's northeast coast. This UNESCO-listed marvel comprises 3,000+ individual reefs and 900 islands, hosting 1,500 fish species, 400 coral types, and endangered marine life like dugongs and green turtles. Climate change-induced bleaching threatens its vibrant ecosystems, yet conservation efforts aim to protect this $6 billion/year eco-tourism treasure. A snorkeling paradise and living laboratory, it remains Earth’s most biodiverse marine wonder.
