"quadruped"的定义和意义

What is "quadruped"?

Quadruped refers to a type of animal that has four legs, such as dogs, cats, and horses. These animals use their four legs for support and locomotion, allowing them to move quickly and easily over a variety of terrains. Quadrupeds are found across many different types of ecosystems, from forests to grasslands to deserts. They are often highly adapted to their environments, with features such as hooves, padded paws, or sharp claws that help them to grip the ground and move efficiently. While quadrupeds are primarily associated with mammals, there are also some species of reptiles and amphibians that move on four legs.
