Ocean animals are diverse and inhabit various marine environments, from shallow coastal waters to the deep sea. They include creatures like fish, whales, sharks, and octopuses. These animals have adapted to their surroundings, developing unique features such as gills for breathing underwater and fins for swimming. Many ocean animals play essential roles in their ecosystems. For example, coral reefs provide habitats for numerous species, while plankton serves as a primary food source for larger animals. Understanding these creatures helps us appreciate the importance of ocean conservation and the need to protect their habitats from pollution and overfishing.
