Giraffe
Giraffa camelopardalis
 
Size Giraffes are one of the tallest land animals, reaching heights of up to 17 feet!
Weight Males generally weigh roughly 2,000 pounds while females typically weigh about 1,250 pounds, but there is wide variation.
Conservation Status On the 2007 IUCN Red List of Threatened Species, the giraffe is listed as Conservation Dependent.
Diet In the wild, giraffes find most of their food among the tops of trees, eating mostly leaves and shoots from many types of trees, including particularly Acacia and Combretum trees, as well as flowers, vines and herbs. A giraffe uses its 18-inch long tongue, which is very strong, to strip leaves from tree branches. Here at the Zoo, giraffes are given specially-formulated pellets and alfalfa hay, as well as branches from honey locust and broad-leafed acacia trees. Keepers also give the giraffes apples and carrots as special treats.

Note: Description below should include Longevity, Behavior, and Reproduction information

Giraffes are best known for their very long necks and the striking coat pattern of irregular brown patches on a lighter background. Each giraffe has a pattern of blotches that is unique to that individual, like a human fingerprint. The pattern may help hide them from predators, particularly when they are young, since the pattern tends to break up their outline when they are among trees. 

Their long necks have seven vertebrae, the same as humans do, and this amazing adaptation allows the giraffe to reach food in tall trees that is not accessible to other browsers. Both sexes have two short, blunt, skin-covered horns atop their heads, although some giraffes can have several more. Males in particular develop additional bumps on the skull as they get older.

Longevity

A few giraffes live into their early 30s, at least in zoos. But just as with humans, dogs, cats, or any other animal, how long an individual giraffe lives varies widely, and most individuals don't reach the maximum age. More typically, a giraffe might live into its late teens or early 20s. Female giraffes seem to tend to live longer than males.

Reproduction

Gestation is about 14 months. Female giraffes generally give birth to a single calf, and since the mother gives birth standing up, and the baby starts life by falling six feet to the ground! Almost immediately after birth, the calf will begin to stand on its own legs and it is typically up and walking in about an hour. Giraffe calves are very vulnerable to predators, so the females often leave their young in groups called creches, which are watched over by a few adults.

Female giraffes are typically reproductively mature by about the age of three and a half, while males may mature a little later. Giraffes generally do not reach full height until two or three years later.


Behavior

Giraffes feed more frequently during the morning and late afternoon hours and usually rest during the remainder of the day. Female giraffe are rarely alone, and are usually found in loose herds of other females where the members come and go freely. Males on the other hand, are more solitary and move between the groups of females.

Although they make various sounds, giraffes rarely make noises other than a soft grunt. Giraffes can run at speeds of up to 35 miles an hour, although their long stride makes them appear to run in slow motion. When it defends itself, a giraffe will kick with its powerful hooves and use its head and head to place a well-aimed blow to its opponent.

Adoption Information


Featured Foster Parent


Twigga is often the one that leads the group - other giraffes will hesitate to go outside if she doesn't go first. Twigga is more cautious than Stella, although food often piques her curiosity.

Stella is very curious and playful; while her keepers are cleaning her pen she often likes to pick up rakes or knock over wheelbarrows.

Fun Facts

A giraffe's heart is two feet long, weighs 25 pounds and pumps up to 20 gallons of blood a minute. Giraffes have special valves in their blood vessels, and their blood vessels are unusually elastic, which helps prevent sudden increases or decreases in blood flow when the giraffe lowers its head all the way to the ground and back up.

Although giraffes have such long necks, they have the same number of vertebrae in the neck that we do - seven.

The giraffe's tongue is 12 to 18 inches long and is black. It has a sticky saliva and feels like sandpaper.
