Marine life encompasses a vast array of organisms that inhabit the world's oceans, from the smallest plankton to the largest whales. These creatures play crucial roles in maintaining the balance of marine ecosystems and contribute to the health of our planet. The diversity of marine life includes fish, mammals, crustaceans, and countless other species, each adapted to their unique environments. Coral reefs, often referred to as the "rainforests of the sea," are particularly rich in biodiversity and provide essential habitats for many marine organisms.
