quadrupod

A quadrupod is an animal that walks on four legs. The term is derived from the Greek words "tetra" meaning four and "podos" meaning foot. Quadrupedal locomotion is a common form of movement among many vertebrate species. This includes mammals, reptiles, amphibians, and some fish. The skeletal structure of quadrupeds is adapted for supporting their body weight and enabling movement across various terrains. This typically involves a four-legged gait, where the limbs move in a coordinated sequence. Different types of gaits exist, such as a walk, trot, canter, and gallop, each varying in speed and efficiency. The presence of four limbs provides stability and allows for a wide range of motion. Many quadrupeds also use their limbs for other purposes, including digging, climbing, or swimming. The evolutionary development of quadrupedalism has played a significant role in the diversification of animal life on Earth.
