digitigrady

Digitigrady is a term used in zoology to describe a type of locomotion in which an animal walks on its digits, with the toes touching the ground. This form of locomotion is common among many mammals, including humans, and is characterized by the weight being borne primarily by the toes and the metatarsal bones, with the heel and the rest of the foot not touching the ground. Digitigrady is often contrasted with plantigrady, where the entire foot touches the ground, and unguligrady, where the animal walks on its hooves or claws.

Animals that exhibit digitigrady include big cats like lions and tigers, as well as many other felids, canids, and even some primates like gibbons. This type of locomotion allows for a more efficient and agile movement, as it reduces the amount of energy required to lift the body off the ground and minimizes the impact on the joints.

In humans, digitigrady is a natural form of walking, as it is the most energy-efficient way to move. However, it is often modified by various factors such as footwear, terrain, and individual biomechanics. The study of digitigrady in humans and other animals is an important area of research in biomechanics and animal behavior.
