Seagrass beds are underwater ecosystems formed by flowering plants that grow in shallow coastal waters. These plants, known as seagrasses, provide essential habitats for various marine species, including fish, crustaceans, and invertebrates. They play a crucial role in stabilizing sediments and improving water quality by filtering pollutants. In addition to supporting marine life, seagrass beds are important for carbon storage, helping to mitigate climate change. They also provide food for herbivores like manatees and sea turtles. Overall, seagrass beds are vital for maintaining healthy ocean ecosystems and supporting biodiversity.
