Masai Giraffe

Giraffa camelopardalis tippelskirchi

About the Masai Giraffe

Geographic Range:

Class:  Mammalia
Order: Cetartiodactyla
Family: Giraffidae
Genus: Giraffa
Species: camelopardalis
Subspecies: tippelskirchi

With its long legs and neck, the Masai giraffe is the world’s tallest land mammal. The giraffe has a huge heart—think of a 25 pound basketball—which generates the high blood pressure necessary to maintain blood flow up to its brain. Males often engage in “necking” —swinging their necks to strike each other with the side of their heads to determine hierarchy or show affection. This roughhousing doesn’t cause physical harm, but when confronted by a predator, giraffes will kick with deadly force in order to escape.

Giraffe Facts

Appearance:
Giraffes are extremely tall, with long legs and flexible necks for reaching treetop leaves. Like humans, giraffes have seven vertebrae in their necks. However, each giraffe vertebra can be over 10 inches long!

Their tails are long with a tassel at the end used to swat insects. On top of their head are two horn-like structures called ossicones.

The Masai giraffe tends to have a darker coat than other giraffe subspecies, but like them its coat is yellowish with jagged-edged, brown patches. These spots can act as camouflage, especially for calves. Dominant males' spots are often darker than those of the rest of the herd. They have long tassled tails, large even-toed hooved feet, two horn-like structures (ossicones), prominent eyes and ears, and blue-black tongues. Prehensile (grasping), tough tongues help them eat thorny leaves. Thick, gooey saliva coats any thorns swallowed.

Like cows, giraffes are ruminant animals, meaning they have more than one stomach to help them digest their food. Giraffes' stomachs have four compartments. They have large hearts (about the size of a basketball, weighing up to 25 pounds) to generate the high blood pressure necessary to maintain blood flow to the brain. Their upper neck has a special regulation system that prevents excess blood flow to the brain when giraffes lower their head to drink. 

Size:
Weight: Males 3,000 pounds; females 1,500 pounds
Height: Males 18 feet; females 14 feet

Diet:
Masai giraffes dine mainly on leaves, bark, twigs, flowers, and fruits. Giraffes especially like leaves from the acacia tree. They use their long, flexible neck to reach the treetops and their long, slick, prehensile tongue to strip the leaves. Giraffes feed and drink primarily in the morning and evening. They are ruminants and wait until the hottest part of the day to chew their cud. Because their legs are longer than their necks, giraffes have to splay their front legs to lean forward in order to drink or graze. Because this puts them in a vulnerable position, trips to the water hole occur in groups. The giraffes take turns watching for predators.

Reproduction:
Giraffes don't have a distinct breeding season. Female giraffes (called cows) mate with the locally dominant male. Females become sexually mature at about 4 years of age.

Gestation:
After a gestation period of 14 to 15 months, the mother gives birth to a single calf while standing up, relying mostly on gravity to facilitate delivery. A newborn calf is about 6 feet tall, weighs 100 to 150 pounds, and is on its feet within an hour of birth. The calf is weaned at 13 months and typically stays with its mother for a year and a half. Sexual maturity is reached at about 4 years of age.

Behavior:
Masai giraffes tend to separate by sex. Female giraffes live in social groups of up to 20, which can include a few young males. Males live in bachelor herds, or as they get older, solitarily. Males often engage in “necking” behavior when they swing their necks around and strike each other with the side of their head. Necking contests determine hierarchy and can also be used to show affection. Surprisingly, necking rarely results in physical harm.

Giraffes are quiet, but they can make a variety of sounds including grunts, hisses, coughs (by courting males), bellows (by females calling their young) and whistles. They have very short sleep requirements, averaging only 1.9 hours per day.  Giraffes rest on their feet.

To defend themselves or to escape, giraffes can kick with deadly force. They can run up to 30 miles per hour by "pacing," which involves the front and back legs on the same side moving forward together and allows the legs on the adjacent side to move forward correspondingly.

Habitat/Range:
Masai giraffes live in savannahs, grasslands and open woodlands--preferably near abundant sources of acacia trees. They range throughout Tanzania and southern Kenya.

Median Life Expectancy:
Males: 13.5
Females: 19.5

Conservation:
Giraffes, an iconic species of Africa, have been going through a silent crisis. In just the past few years, their numbers in the wild have dropped dramatically with little notice. Giraffe numbers have decreased by approximately 40 percent, and there are less than 100,000 giraffes left throughout Africa. Threats include habitat loss, habitat degradation, habitat fragmentation, population growth and poaching. Despite these alarming figures, giraffes have received a surprisingly small amount of research, particularly when compared to other large animals including elephants and rhinos.

A 2016 report published in Current Biology uncovered some unexpected findings on the status of giraffes. Up to this point, only one species of giraffe, comprised of several subspecies, had been known to exist. Taking into account skin biopsies on 190 giraffes throughout Africa, this study found that there are, in fact, four very distinct species. These four species include northern giraffe, southern giraffe, reticulated giraffe, and Masai giraffe. It's been reported that the differences among giraffe species are as great as those between polar bears and brown bears.

With these new findings, the hope is that giraffe conservation will gain new attention on the global map. AZA- accredited zoos and their partners are working collectively to help save giraffes through education, scientific research, field work, public awareness and action.

Fun facts:

  • The giraffe is the tallest land mammal.
  • Giraffes are related to the okapi.
  • The giraffe was once called the “camel-leopard” because of its spotted pattern and small hump on its back, hence its species name.

AZA SAFE: Saving Animals from Extinction

We're proud to support the Association of Zoos and Aquariums' SAFE initiative: A commitment to harness our collective resources, focus on specific endangered species (including giraffes), and save them from extinction by restoring healthy populations in the wild. More

Species Survival Program

Zoo New England participates in the Masai giraffe Species Survival Plan. By sharing research and knowledge, participating institutions work together to establish guidelines that best ensure the health of captive populations, and with success, the survival of otherwise extinct species.

Reticulated Giraffe Project

We've supported a number of organizations in support of giraffe conservation, including the Reticulated Giraffe Project, the White Oak Conservation Foundation, Wildlife Conservation Global, and the Sahara Conservation Fund. The Zoo also hosts yearly events on World Giraffe Day to raise funds and awareness for the species.

Quarters for Conservation

Through our Quarters for Conservation program, from July, 2018 through January, 2019, a portion of every admission ticket and membership sold will help support AZA's SAFE Giraffe initiative.

You Can Help!

  • The U.S. is the number one importer of giraffe trophies and parts. There is no U.S. law or international treaties that protect the giraffe. Petition the U.S. Fish and Wildlife Service to list the giraffe as endangered under the U.S. Endangered Species Act.
  • Take the pledge not to purchase giraffe products of any kind.
  • Educate your friends and family about the plight of this iconic species
  • Learn how to go green, protect the environment and fight global warming with 45 easy to follow tips.
