Velociraptor
Velociraptor was a type of dromaeosaurid dinosaur (bird-like dinosaur). There were two species of Velociraptor that lived in Central Asia 75 to 71 million years ago (end of Cretaceous period). First fossil of Velociraptor was discovered in 1923 in a Gobi Desert in Mongolia. Second species has been discovered in 2008 in China. Velociraptor lived in arid, sandy areas. It became very popular and widely recognized after the movie "Jurassic Park", even though it wasn't portrayed correctly (Velociraptor wasn't extremely intelligent, large and covered with scaly skin).
Interesting Velociraptor Facts:
Velociraptor was able to reach length of 6.6 feet and weight of 33 pounds.
Velociraptor had large, up-curved skull that was concave on the upper surface and convex on the bottom side. It had long, narrow snout and two large hand-shaped appendages with three curved claws. These appendages were anatomically very similar to the wing bones of modern birds. Velociraptor had long, inflexible tail whose main purpose was to provide balance.
Name "Velociraptor" means "swift thief". Name refers to the ability of this dinosaur to quickly grab its prey.
Hind feet of Velociraptor were equipped with sharp claws. 3-inches-long, sickle-shaped claw on the second toe was used for killing and to prevent escape of the prey.
cheetah
The cheetah is the fastest land animal in the world. They can reach a top speed of around 113 km per hour.
A cheetah can accelerate from 0 to 113 km in just a few seconds.
Cheetahs are extremely fast however they tire quickly and can only keep up their top speed for a few minutes before they are too tired to continue.
Cheetahs are smaller than other members of the big cat family, weighing only 45 – 60 kilograms.
One way to always recognise a cheetah is by the long, black lines which run from the inside of each eye to the mouth. These are usually called “tear lines” and scientists believe they help protect the cheetah’s eyes from the harsh sun and help them to see long distances.
Cheetahs are the only big cat that cannot roar. They can purr though and usually purr most loudly when they are grooming or sitting near other cheetahs.
While lions and leopards usually do their hunting at night, cheetahs hunt for food during the day.
A cheetah has amazing eyesight during the day and can spot prey from 5 km away.
Cheetahs cannot climb trees and have poor night vision.
With their light body weight and blunt claws, cheetahs are not well designed to protect themselves or their prey. When a larger or more aggressive animal approaches a cheetah in the wild, it will give up its catch to avoid a fight.
Cheetahs only need to drink once every three to four days.
