Fully grown giraffes stand 5–6 m (16–20 ft) tall, with males taller than females.[14] The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female[29] 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.[30] Despite its long neck and legs, the giraffe’s body is relatively short.[31]:66 Located at both sides of the head, the giraffe’s large, bulging eyes give it good all-round vision from its great height.[32]:25 Giraffes see in color[32]:26 and their senses of hearing and smell are also sharp.[15] The animal can close its muscular nostrils to protect against sandstorms and ants.[32]: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.[32]: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.[14]
