Giraffes

A giraffe has only two gaits: walking and galloping. Walking is done by moving the legs on one side of the body at the same time, then doing the same on the other side.
When galloping, the hind legs move around the front legs before the latter move forward, and the tail will curl up.
The animal relies on the forward and backward motions of its head and neck to maintain balance and the counter momentum while galloping.
The giraffe can reach a sprint speed of up to 60 km/h (37 mph), and can sustain 50 km/h (31 mph) for several kilometres.
