Terrestrial animals are species that primarily live on land rather than in water or air. They have adapted to various environments, including forests, deserts, grasslands, and mountains. Examples of terrestrial animals include lions, elephants, and kangaroos. These animals have developed features such as legs for walking, breathing systems suited for air, and skin or fur that helps them survive in their habitats. Most terrestrial animals are part of the animal kingdom and can be classified into different groups, such as mammals, reptiles, birds, and insects. They play essential roles in their ecosystems, contributing to processes like pollination, seed dispersal, and maintaining food chains. Understanding terrestrial animals helps us appreciate biodiversity and the importance of conservation efforts.
