The three-toed sloth (Bradypus tridactylus) of tropical South America has an average ground speed of 1.8–2.4 m (6–8 ft) per minute (or 0.1–0.16 km/h; 0.07–0.09 mph), but in the trees it can "accelerate" to 4.6 m (15 ft) per minute (or 0.27 km/h; 0.17 mph).

Compare this to the fastest mammal on land, the cheetah (Acinonyx jubatus), which has registered speeds of 28.7 m/s (103.5 km/h; 64.3 mph) over short distances.
