A team of Australian scientists has discovered a coral reef that is taller than the Empire State Building. The newly found coral reef is 500 meters tall, and its base is 1.5 kilometers wide. According to the scientists, its tallest point comes to about 40 meters below the surface of the ocean.

The scientists found the enormous coral reef during a 12-month expedition to explore the ocean around Australia. They made the discovery while using an underwater robot to explore the Great Barrier Reef and map the sea floor. The Great Barrier Reef is the world’s largest coral reef and is home to about 2,000 species of fish, corals, and other animals. It became a World Heritage site in 1981.

Scientist Wendy Schmidt said that our knowledge about the ocean is limited, but new technology is helping us learn more. A number of other amazing discoveries were made in 2020. In April, scientists found the longest animal ever seen in the ocean, a 47-meter siphonophore [sai-FAH-nuh-for]. Over 30 new species were also discovered during a different deep sea expedition.
