Fully grown giraffes stand 5–6 m (16–20 ft) tall, with males taller than females. The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female with maximum weights of 1,930 kg (4,250 lb) and 1,180 kg (2,600 lb) having been recorded for males and females respectively. Despite its long neck and legs, the giraffe’s body is relatively short.:66 Located at both sides of the head, the giraffe’s large, bulging eyes give it good all-round vision from its great height.:25 Giraffes see in color:26 and their senses of hearing and smell are also sharp. The animal can close its muscular nostrils to protect against sandstorms and ants.:27 The giraffe’s prehensile tongue is about 50 cm (20 in) long. It is purplish-black in color, perhaps to protect against sunburn, and is useful for grasping foliage, as well as for grooming and cleaning the animal’s nose.:27 The upper lip of the giraffe is also prehensile and useful when foraging. The lips, tongue, and inside of the mouth are covered in papillae to protect against thorns.
