Did you know that Emus don’t walk backwards? As large flightless birds, emus are capable of sprinting over long distances and can reach speeds up to 48km/hr. They are able to do so because of an adaptation in their legs that is not present in other birds, the gastrocnemius muscle (calf). Although the reason behind their inability to walk backwards is still unknown, it’s speculated that the knee joint simply prevents them from moving in that direction.
