Our selection of the five most impressive mammals of South America. Whilst not quite as dangerous as their African counterparts, the South American Big Five are still spectacular animals to see in the wild. With males weighing twice as much as the leopard equivalent, jaguars justly head the list followed by the mountain lion or puma. Giant anteaters are graceful wanderers of the open plains whereas giant river otters are feared pack hunters of the continents waterways. Finally, tapirs are short-sighted, timid animals but one which you would never wish to corner.
