White Rhinoceros
The white rhinoceros is the largest of the five species of rhinoceros and the world's largest land mammal after the three species of elephant. It has a massive body and large head, a short neck and broad chest. The head and body length is 3.7 to 4 m (12 to 13 ft) in males and 3.4 to 3.65 m (11 to 12.0 ft) in females, with the tail adding another 70 cm (28 in) and the shoulder height is 1.7 to 1.85 m (5 ft 7 in to 6 ft 0.8 in) in the male and 1.6 to 1.77 m (5 ft 3 in to 5 ft 10 in) in the female. Weight in this animal typically ranges from 1,360 to 3,630 kg (3,000 to 8,000 lb). The male, averaging 2,300 kg (5,100 lb) is heavier than the female, at an average of 1,700 kg (3,700 lb).[17][18][19] The largest recorded white rhinoceros was about 4,500 kg (9,900 lb). On its snout it has two horn-like growths, one behind the other. These are made of solid keratin, in which they differ from the horns of bovids (cattle and their relatives), which are keratin with a bony core, and deer antlers, which are solid bone. The front horn is larger and averages 90 cm (35 in) in length, reaching as much as 150 cm (59 in). The white rhinoceros also has a noticeable hump on the back of its neck. Each of the four stumpy feet has three toes. The color of the body ranges from yellowish brown to slate grey. Its only hair is the ear fringes and tail bristles. White rhinos have a distinctive broad, straight mouth which is used for grazing. Its ears can move independently to pick up sounds but it depends most of all on smell. The olfactory passages which are responsible for smell are larger than their entire brain. The white rhinoceros has the widest set nostrils of any land based animal.
Indian Rhinoceros
Among terrestrial land mammals native to Asia, the Indian rhinoceros is second in size only to the Asian elephant. This heavily built species is also the second-largest living rhinoceros, behind only the white rhinoceros. Males have an average head and body length of 368–380 cm (12.07–12.5 ft) with a shoulder height of 163–193 cm (5.35–6.33 ft), while females have an average head and body length of 310–340 cm (10.2–11.2 ft) and a shoulder height of 147–173 cm (4.82–5.68 ft).[4][verification needed] The weights of captive individuals from the Basel Zoo were around 1,600 kg (3,500 lb) on average for the females and around 2,100 kg (4,600 lb) on average for the males. The skull is heavy with a basal length above 60 cm (24 in) and an occiput above 19 cm (7.5 in). The largest sized specimens can range up to 4,000 kg (8,800 lb). The rhino's single horn is present in both males and females, but not on newborn young. The black horn is pure keratin, like human fingernails, and starts to show after about six years. In most adults, the horn reaches a length of about 25 cm (9.8 in), but has been recorded up to 57.2 cm (22.5 in) in length. The nasal horn is slightly back-curved with a base of about 18.5 cm (7.3 in) by 12 cm (4.7 in) that rapidly narrows until a smooth, even stem part begins about 55 mm (2.2 in) above base. In captive animals, the horn is frequently worn down to a thick knob. The Indian rhinoceros has thick, silver-brown skin, which becomes pinkish near the large skin folds that cover its body. Its upper legs and shoulders are covered in wart-like bumps. It has very little body hair, aside from eyelashes, ear fringes and tail brush. Males develop thick neck folds.
