Do you know what an animal is? It's a living thing that moves around, like birds, lions and gazelles. Some animals are really fast and can run, fly or swim quickly.
The fastest animal is called a peregrine falcon. It is a bird that can fly very fast. Do you know how fast it can fly? It can fly up to 240 miles per hour! That's as fast as a car on the highway.
The peregrine falcon has special features that help it fly so fast. It has long, narrow wings that make it aerodynamic, which means it can cut through the air easily. It also has sharp eyesight, which helps it see its prey from far away.
But there are other animals that are really fast too. For example, the cheetah is the fastest land animal. It can run up to 70 miles per hour! That's faster than most cars on the road.
There are also some animals that are really fast in the water, like sailfish and marlins. They can swim up to 60 miles per hour. Can you imagine swimming that fast?
So, there are many fast animals out there, but the peregrine falcon is the fastest of them all.
