Coral reefs are considered the "rainforests of the sea" because they are incredibly diverse ecosystems that support a wide variety of marine life, similar to how rainforests support a vast array of plant and animal species on land. Coral reefs are home to numerous species of fish, invertebrates, and other marine organisms, making them one of the most biologically rich environments in the ocean. Just like rainforests, coral reefs are also important for providing oxygen, food, and protection for many species, and they play a crucial role in maintaining the overall health of the marine environment.
