A series of valves in a giraffe's neck stops blood from rushing to its head when it bends down to drink.
Description: The Giraffe is the tallest land animal on earth with a long neck that contains only seven vertebrae (just like humans!). They have a long, strong tongue which is used to pull leaves from branches and is about 45 cm long.
Giraffe have a thick spotted coat and a long tail which is useful for brushing away flies. The Giraffe can have up to five blunt, short horns called ‘ossicones’.
Diet: Giraffe are herbivores. Because of their long necks they are able to eat the leaves from taller trees such as acacia and wild apricot which gives them an advantage over other herbivores. They also eat shoots, fruit and other vegetation. Giraffe are also known as browsers.
In the wild: Female Giraffe, or ‘cows’, mate with local dominant males, ‘bulls’. These bulls compete with each other by swaying and curling necks. Newborns are kept away from the main herd by the mother for the first 10–30 days and weaning takes place by 13 months. Lions, Spotted Hyaenas and leopards are the natural predators of young Giraffe.
Threats: Traditional hunting, poaching for the tourist trade and habitat loss have contributed to the declining numbers and, in some cases, the complete extinction of Giraffe from some areas of their former range.
Saving wildlife together: Eight Giraffe have been born at Perth Zoo since 1995, with the latest birth on 16 January 2012.
