FOUR-HORNED ANTELOPE and INDIAN SMOOTH OTTER 
(Tctraceros duadricornh and Lutra macro Jus) 
The Four-Horned Antelope is the only living four-horned wild 
mammal, though fossil mammals with four horns are known, and a 
variety of domestic sheep has developed this double number. It is found 
in pairs or small groups in hilly, lightly wooded country near water. 
It is unknown in Ceylon and east of the Bay of Bengal. 
The Otters, of which several species are known in India, are 
essentially weasels which have taken to water and grown larger. Their 
toes are webbed and they are good swimmers and divers. In some parts 
of Asia, Otters are kept tame and used for catching fish or to drive 
them into nets.
