Tigers use their tails for balance when they run through fast turns. They also use their tails to communicate with other tigers.

Turtles existed
even before the dinosaurs! Some turtles can live up to 200 years old!

The Crocodile is the largest of all living reptiles! It can measure up to 8 meters long! Some can live up to 100 years old! The major difference between a crocodile and an aligator is the teeth! The Crocodile always seems to be smiling because you can always see its teeth!

Polar bears are just as smart as apes!
The polar bear is so well insolated against the cold that they sometimes get hot when running!

When a frog swallows a meal, his bulgy eyeballs will close and go down into his head! This is because the eyeballs apply pressure and actually push a frog's meal down his throat!

Giraffes are the tallest land mammals in the world. The neck of an adult giraffe is about six feet long (1.8 meters), and is extremely muscular. Giraffes can go for days without water. Besides the lion, crocodiles are natural enemies of giraffes.
The spots on each giraffe are distinctive to that animal alone. Because of this, people who are familiar with giraffes can often identify each animal merely by recognizing their spot patterns.
