FAST FACTS

Cheetahs are built for speed.

The world's FASTEST land mammal. Cheetahs run quick short bursts up to 70 mph (113km/hr). Reaching 45 mph is just 2 seconds.

How do cheetahs run so FAST?

Outer Workings

Long Flat Tails
A long tall helps them balance and steer their bodies when running. Their tails are flat and  act like a rudder on a boat because it helps direct them and keeps them from spinning out of control when running.
Spring-like Backbone
A spring-like backbone helps cheetahs burst forward and it is flexible so it can move easily when running to catch its prey.
Long Powerful Legs
Their long very powerful legs can cover up to 20 feet in one stride helping them gain speed quickly. These powerful legs help them change directions faster than any other land animal.
Lean Muscular Bodies
Their lean muscular bodies help them move quickly and fast.
Semi-Retractable Claws
Semi-retractable claws (similar to claws on dogs) give cheetahs the ability to grip the hard ground.  They also have hard pads with ridges on the bottom of their paws that help provide traction with better gripping and less slipping.
Narrow Heads
Their narrow head helps them move through the air (aerodynamics) easier. This reduces the amount of drag or wind resistance that could slow them down when running.

Inner Workings

Bigger Inner Ear Canals
Cheetahs' bigger inner ear canals allow them to keep their heads steady and solid during running. This helps them keep their eyes steady on the prey they are chasing and aids in their ability to successfully catch food.
Larger Nostrils
Cheetahs have larger nostrils that allow for lots more air to flow into their noses and lungs. This helps support their bodies while running.
Enlarged Hearts
An enlarged heart can push (circulate) more blood through the body. Heart and lungs work together to push oxygen through their blood quicker.
Larger Lung Capacity
Larger lung capacity means cheetahs can breathe a lot bigger and deeper to support their quickness while running.
Cheetah Tidbits
When the cheetah runs at one point during its long stride, ALL four legs of a cheetah are OFF the ground. Looks like it could be flying! Amazing!

Just the Science

Scientific Name of Cheetahs
Acinonyx jubatus
Cheetah Conservation Status
United States Endangered Species Act (ESA) of 1973 Cheetahs are listed as ENDANGERED Environmental Conservation Online System (ECOS) International Union for Conservation of Nature (IUCN) Red List: Cheetahs are Vulnerable with decreasing populations (last assessed 2014) Convention on International Trade on Endangered Species (CITES) 183 parties agree to a framework to ensure the sustainability of the trade in order to safeguard these resources for the future and safeguard certain species from over-exploitation. Cheetahs is a CITES-listed species (Appendix I)
World Cheetah Population
Currently less than 7,500 cheetahs left in the world.
