Animals are living creatures that belong to the kingdom Animalia. They come in many shapes and sizes, from tiny insects to large whales. Animals can be found in various habitats, including forests, oceans, and deserts. They play important roles in ecosystems, helping to maintain balance in nature. Most animals can move on their own and have senses to help them interact with their environment. Some animals, like dogs and cats, are domesticated and live with humans, while others, like lions and eagles, live in the wild. Each animal has unique characteristics that make it special and important to our world.
