 Lateral sequence gaits during walking and running are most common in mammals, but arboreal mammals such as monkeys, some opossums, and kinkajous use diagonal sequence walks for enhanced stability.Diagonal sequence walks and runs (aka trots) are most frequently used by sprawling tetrapods such as salamanders and lizards, due to the lateral oscillations of their bodies during movement.Bipeds are a unique case, and most bipeds will display only three gaits—walking, running, and hopping—during natural locomotion.
