Giant Anteater

  The giant anteater is the largest species of anteater. It is a solitary animal, found in grasslands, deciduous forests and more. It feeds mainly on ants and termites, eating up to 30, 000 in a day. The giant anteater is one of the few animals without any teeth, even as an adult. Instead, it crushes insects, using hard growths found on the inside of its mouth( that are not teeth) and flabby stomach.
  They have one of the lowest body temperatures of all living mammals, around 32.7^oC. When threatened, the giant anteater will stand up on its hind legs and rapidly strikes with its claws or hugs the attackers like a bear. The adult anteater is able of fending off and even killing its main predators, big cats such as the cougar and jaguar.
  The giant anteater grows to a size of up to 7 feet (2.1 m) in length, with a 4-foot-long (1.2 m) head and torso, and a 3-foot-long (0.91 m) tail. On average, it weighs from 65 to 140 pounds (29 to 64 kg)
