Coral reefs are often referred to as the rainforests of the sea due to their high levels of biodiversity and the important role they play in supporting marine ecosystems. Just like rainforests on land, coral reefs are home to a wide variety of plant and animal species, making them one of the most diverse ecosystems in the ocean. Additionally, coral reefs are crucial for supporting marine life and are often considered the "underwater cities" due to the numerous species that depend on them for food, shelter, and protection.
