Rhinoceros
Modern rhinoceroses are large animals, ranging from 2.5 metres (8 feet)
long and 1.5 metres (5 feet) high at the shoulder in the Sumatran
rhinoceros (Dicerorhinus sumatrensis) to about 4 metres (13
feet) long and nearly 2 metres (7 feet) high in the white rhinoceros.
Adults of larger species weigh 3–5 tons. Rhinoceroses are noted for
their thick skin, which forms platelike folds, especially at the
shoulders and thighs. All rhinos are gray or brown in colour, including
the white rhinoceros, which tends to be paler than the others. Aside
from the Sumatran rhinoceros, they are nearly or completely hairless,
except for the tail tip and ear fringes, but some fossil species were covered with dense fur. The feet of the modern species have three short toes, tipped with broad, blunt nails.
