Giraffe


Now let me tell you about the facts of giraffe.
Giraffe is well-known for tall profile, their long neck, and their pattern. Despite giraffe being easily recognizeable, there are facts about giraffe that make them worth a closer look.

Giraffe is the tallest of all living land animals. The height is nearly 6 m or 19ft. Their long neck consists of just seven vertebrae, same with other mammals, but in giraffe each neck vertebrae is greatly elongated.



The okapi is the closest living relative to the giraffe. Giraffe belong to the family Giraffidae. Giraffeidae is subdivided into two subgroups, the genus Giraffa and the genus Okapia.


Giraffe prefer habitat where there is an abundance of acacia trees on which they feed. Giraffe has a preference for feeding on young leaves but will eat grasses and other plant matter.



Giraffe has short horns on their head also known as ossicones. Both male and female giraffes have horns. The ossicones of giraffes remain covered by skin and fur. Ossicones can help to distinguish between male and female giraffe. Females have hair on the top of the ossicones. Males usually have bare-topped ossicones (the hair often worn away during combat with other males)

White giraffe is extremely rare and are not albinos. All of these white giraffes have had some pigmentation, either dark eyes or pattern.no true albino giraffe have ever been discovered.





Giraffes have longer forelegs than hind legs.






A giraffe’s heart has high enough pressure to pump blood up the giraffe’s long neck to its head. But when giraffe lowers its head it risks injury due to excessive blood pressure. To counter this, giraffes have pressure-regulating system which restricts the amount of blood that rushes towards the brain when the giraffe lowers its head.
