Tropical marine ecosystems are vibrant environments found in warm ocean waters near the equator. They are characterized by diverse habitats, including coral reefs, mangroves, and seagrass beds. These ecosystems support a wide variety of marine life, including fish, invertebrates, and marine mammals, making them some of the most productive areas on Earth. Coral reefs, often referred to as the "rainforests of the sea," are particularly important within tropical marine ecosystems. They provide shelter and food for many species, while also protecting coastlines from erosion. However, these ecosystems face threats from climate change, pollution, and overfishing, which can disrupt their delicate balance.
