This article is about the body structure. For the unit of measurement see
Foot (unit).
Land vertebrates have feet. The organization of their feet varies. Two factors come into play: weight and lifestyle.
1. Plantigrade: heavy animals usually put their heels down to support their weight.
2. Unguligrade: large animals with hooves.
3. Digitigrade is usually reserved for lighter animals. It means to walk on the toes.
