Beneath the ocean's surface, stretching across coastal waters worldwide, lies one of Earth's most productive yet underappreciated ecosystems: seagrass meadows . 01. What Are Seagrasses? Seagrasses are flowering plants that originated on land and spread to marine habitats about 100 million years ago. They are not actually grasses.

There are roughly 72 species of seagrasses in the world, which are divided into four main groups: Posidoniaceae, Cymodoceaceae, Hydrocharitaceae, and Zosteraceae. Seagrasses can photosynthesize underwater, have evolved specific systems for pollen transfer in water and have adapted to flourish in saline environments. Mediterranean Posidonia oceanica like seagrass species, are among the oldest living things on Earth, with a lifespan of thousands of years. 02. What Are The Ecological Importance of Seagrass Meadows?
