Water creatures are animals that live in or depend on water for their survival. They can be found in oceans, rivers, lakes, and ponds. Common examples include fish, frogs, and crabs. These creatures have adapted to their aquatic environments, often developing features like gills for breathing underwater or fins for swimming. Many water creatures play important roles in their ecosystems. For instance, plankton serves as a primary food source for larger animals, while coral reefs provide habitats for diverse marine life. Understanding these creatures helps us appreciate the balance of life in our planet's water bodies.
