            The giraffe is the tallest animal on Earth. Male giraffes grow up to 18 feet tall (up to 5.5 meters) and weigh roughly 1 to 2 tons. The female giraffe grows up to 16 feet tall (up to 4.5 meters).

          A newborn giraffe will measure about 6 feet tall and grow about an inch per day, doubling its height in the first year. The front legs of a giraffe are slightly longer than the back legs.  All giraffes have dark brown eyes, except when a rare albino baby is born. An 'albino baby' would have 'pink' eyes. 
       
          Giraffes have horns blunted in which male giraffe horns are thicker and heavier with a length of about 12 cm, which is used to fight with rival males. Some giraffe species have five horns on their heads.








        They are belong to herbivore animals, so they eat leaves. They are big mammals, but they're tame. Giraffes have very long neck and legs. Their tall body help them to identify their enemies (especially lions) while their enemies are hiding around them. The attacks of carnivores are rarely happened because of their big body and strong kick. Giraffes are Africa's endemic animal. They usually live in savannas, grasslands, and other open areas in tropical zone. Their foods are leaves on trees. Their tall body help them eat leaves in high places that can't be gotten by other species. 


Unique things :
1.  A giraffe’s heart can weigh more than 24 pounds and pumps approximately 16 gallons per minute.
2. The giraffe has twice as many blood corpuscles (blood cells) than humans do.
3. Giraffes only reach a deep sleep for between 1 and 12 minutes.  In deep sleep the neck is bent backward like a handle, the chin touches the ground behind the tarsal joint of the stretched hind leg, and the lower jaw rests on the shank.


When giraffe sleep
4.  Usually giraffes rest standing up, flicking their ears and keeping one eye open alternately to keep alert as they to be ready to run away in an instant.
5. A giraffe’s tongue is like a hand (prehensile), about 24 inches long and black in colour. They also have flexible tounge to help them fetch leaves. Giraffes have exceptionally long tongues that are blue-black in color.


6. Giraffes drink water if it is available but can go weeks without it. Otherwise they rely on the morning dew and the water content of their food. At the water hole, up to 12 gallons may be taken in at once. While drinking, they open their legs to form inverted V.




7. The word ‘giraffe’ comes from an Arabic word, ‘zirafah’ which means “the tallest of all”.
