Foot
weight-bearing anatomical structure found in vertebrates / From Wikipedia, the free encyclopedia
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.
