A two-year old meerkat sits in its cage at the Buenos Aires' Zoo, July 30,
2002. Meerkats are mammals with dark eyes that are lined by dark fur, making
them appear to be wearing built-in sunglasses. They can live in the wild for
up to ten years and in captivity for 15, reaching a height of 12 inches (30
centimeters) and weighing two pounds (900 grams). Considered intelligent and
communicative animals, they flourish in their environment and are not
endangered. Five of the mammals arrived on an exchange from a Johannesburg
zoo. REUTERS/Enrique Marcarian
