Kenya is a hotspot for Giraffe in East Africa and has an estimated 29,000 giraffes which account for almost 30% of Giraffe in Africa. There are 9 giraffe sub-species, Kenya is home to three species of giraffe: the reticulated giraffe, Masai giraffe (Giraffa tippelskirchi) and Nubian giraffe subspecies (G. c. camelopardalis). 1. They are the tallest mammals on Earth Their legs alone are taller than many humans-about 6 feet. A giraffe's neck alone is 6 feet (1.8 meters) long and weighs about 600 lbs. (272 kilograms). Females grow up to 14 feet (4.3 m) tall and weigh up to 1,500 lbs. (680 kg), while males grow up to 18 feet (5.5 m) tall and weigh up to 3,000 lbs. (1,360 kg). They can run 35 mph (56 km/h) in short bursts and run for longer stretches at 10 mph (16 km/h), according to National Geographic. 2. No two giraffes are the same Just like human fingerprints and zebra stripes, the coat pattern of a giraffe is unique to that animal. 3. Giraffes love to hang out in towers Giraffes are so social that they don't have territories. A group of giraffes is aptly called a tower, according to the U.S. Geological Survey. Towers typically have 10 to 20 members. Who lives in the tower can vary. Some towers consist of all females and their young, or all male or mixed genders. Members are free to come and go as they please. 4. They are experts in power naps Giraffes only sleep around 20 minutes or less per day, according to PBS Nature. Staying awake most of the time allows them to be constantly on alert for predators. They usually get their sleep-in quick power naps that last just a couple of minutes. 5. They like their food in greens and don’t drink much water Giraffes are herbivores, which means they eat only plants. Their long necks allow them to reach leaves, seeds, fruits, buds and branches high up in mimosa and acacia trees. They can eat hundreds of pounds of leaves per week, according to National Geographic. They can guzzle up to 45kg of leaves and twigs a day. Their tongues are a substantial 21 inches (53 centimetres) long. Giraffes don’t drink much water because they get most of their water from their leafy meals, and only need to drink once every few days. 6. They can go without drinking for weeks Though these animals eat a lot, giraffes can go without drinking for weeks at a time. They get most of their moisture from the vegetation they eat.
