reach 520 pounds, which was the weight of a ten-year-old male 
that died in the Bronx Zoo. The young at birth have a spotted 
and striped pattern of yellow-brown mixed with blackish brown, 
but they change to a mature coloring in the first year. One or two 
are born at a time. Tapirs are rather solitary animals living 
in swampy, often very wet forest. The range includes the Malay 
Peninsula as far north as Tenasserim. 
THE RHINOCEROSES (FAMILY RHINOCEROTIDiE) 
These huge, ungainly creatures with their armor-plated hides, 
their massive legs, their odd-looking heads, their ears placed 
far back and their eyes far forward, and the bosses or horns on 
their noses, are sufficiently well known to need little further 
description. 
The skin plates, very thick and relatively inflexible, work 
against one another along suture-like contact lines where there 
is much thinner, pliable connecting skin. The horns on the nose 
are not made of bone. They are special structures derived from 
the fusing or cementing together of hairs. Three broad, hoof- 
like toes, of which the middle one is the largest, are present on 
both front and hind feet. There are two nipples under the belly. 
Only one calf is born. The senses of smell and hearing are very 
acute in Rhinoceroses ; sight is reputed to be weak. When attack- 
ing an enemy, Rhinos are said to bite severely with their incisor 
teeth, as well as to strike with the horn. 
Fables have it that the Rhinoceros is the deadly enemy of the 
Elephant. In The Arabian Nights, the Rhinoceros, after stab- 
bing its horn into the underparts of the elephant, carried that 
animal about on its head until blinded by the juices running 
down from the elephant's body. 
There are still several living species of Rhinoceroses. The 
African two-horned Rhinos are placed in the genus Dicer os.
