Coral reefs host millions of bacteria, revealing Earth’s hidden biodiversity

According to a study, coral reefs in the Pacific Ocean contain approximately 3 million types of bacteria, highlighting the underestimated diversity of Earth's microbiome. The research conducted during the Tara Pacific Expedition examined samples from 99 coral reefs and found a vast array of bacterial species. Understanding the microbial biodiversity in reefs is important for conservation and maintaining the health of these ecosystems.
