Giraffes tower over Africa's plains. These tall animals are identified by their long necks, equally long and spindly legs, and spotted coats. Most giraffes have a tan, white or yellow coats that are spotted with brown, square shapes.

Giraffes are the tallest living animals in the world, according to the Smithsonian National Zoological Park. A giraffe's neck alone is 6 feet (1.8 meters) long and weighs about 600 lbs. (272 kilograms). The animal's legs are also 6 feet long.

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).

With such a massive body, it makes sense that the giraffes' organs and other body parts are equally huge. Their tongues are a substantial 21 inches (53 centimeters) long, and their feet are 12 inches (30.5 cm) across. According to the San Diego Zoo, a giraffe's heart is 2 feet (0.6 m) long and weighs about 25 lbs. (11 kg). Their lungs can hold 12 gallons (55 liters) of air. In comparison, the average total lung capacity for a human is 1.59 gallons (6 liters).
