Unipedalism

Person or creature with one foot and one leg

A uniped (from Latin uni- "one" and ped- "foot") is a person or creature with only one foot and one leg, as contrasted with a biped (two legs) and a quadruped (four legs). Moving using only one leg is known as unipedal movement. Many bivalvia and nearly all gastropoda molluscs have evolved only one foot.
