A "quadruped" is an animal that walks on four limbs. This term is commonly used to describe many mammals, such as dogs, cats, and horses. Quadrupeds have evolved to move efficiently on land, using their four legs for balance and speed. Quadrupeds can be found in various habitats, from forests to grasslands. Their body structure typically includes a strong spine and limbs that support their weight. Some quadrupeds, like cows and deer, are herbivores, while others, like lions and wolves, are carnivores. This diversity allows them to adapt to different environments and ecological roles.
