Uniped

The term uniped (from Latin "uni" = one + "ped" = foot) refers to 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 know as unipedal movement.

The number of locomotory appendages varies much between animals, and sometimes the same animal may use different numbers of its legs in different circumstances. The best contender for unipedal movement is the springtail, which while typically hexapedal, hurls itself away from danger using its furcula, a tail-like forked rod that can be rapidly unfurled from the underside of its body.

In fiction and mythology

In the Saga of Eric the Red, a native of Vinland who is described as being one-legged kills one of Eric's men. In the children's fiction book "They Came on Viking Ships" by Jackie French, a uniped is a one-legged Norse mythical creature that lived in the south of Vinland during the time of the expedition of Freydís Eiríksdóttir.

The sciapod was another mythical one-legged humanoid.

There are also one legged creatures in "". In "The Adventures of Gomby and Son", Gomby meets a traveller at the Forest of Zann who is unileg.
