Giant anteaters have very poor eye site but their noses are so sensitive, they can distinguish which species of termite lie within a mound. After locating a source of termites, claws 4 inches long are used to dig into the mound, before a 2 foot tongue is used to reach them. On an average day a Giant ant eater can eat 35,000 termites. South America is a land of extremes, many hundred thousand square miles of forests, grasslands and mountains.
