Step-by-step explanation:
Pigs are plantigrade animals.
Plantigrade refers to animals that walk on the soles of their feet, with the entire foot making contact with the ground. They use the entire length of their limbs to support their body weight while moving. Examples of plantigrade animals include humans, bears, and raccoons.
In contrast, digitigrade animals walk on their toes, with only the digits touching the ground. Cats and dogs are examples of digitigrade animals. Unguligrade animals walk on the tips of their toes, and their hooves provide support. Hoofed animals like deer, sheep, goats, and giraffes are unguligrade.
