Tamandua is a genus of anteaters. It has two members: the Southern Tamandua (Tamandua tetradactyla) and the Northern Tamandua (Tamandua mexicana). They live in forests and grasslands, are semi-arboreal, and possess partially prehensile tails. They mainly eat ants and termites, but they occasionally eat bees, beetles, and insect larvae. In captivity, they will eat fruits and meat. They have no teeth and depend on their powerful gizzard to break down their food.

The Northern Tamandua ranges from southeastern Mexico south throughout Central America, and in South America west of the Andes from northern Venezuela to northern Peru. Southern Tamanduas are found from Venezuela and Trinidad to northern Argentina, southern Brazil and Uruguay.

Tamanduas have a tapered head with a long, tubular mouth with an opening only as wide as the diameter of a pencil, from which the tongue is protruded. They also have thick, bristly fur, which is yellowish-white, with a broad black lateral band, covering nearly the whole of the side of the body. Northern Tamanduas have a black V going down their backs, while Southern Tamanduas only have the V in the southeastern part of their range, which is the farthest from the Northern Tamandua's range. The underside and end of the tamanduas' tails are hairless, and they have four clawed digits on the forefeet and five on the hind feet.

Tamanduas grow to be 535-880 mm, plus an additional tail length of 400-590 mm. They weigh between 2 and 7 kg and live up to 9 years. The tamandua is thought to nest during the day in hollow tree trunks or in the burrows of other animals. Research shows that this type of anteater spends 13-64% of its time in trees. In fact, they are very clumsy on the ground unlike their cousin, the giant anteater. To avoid puncturing their palms with their sharp claws, they walk on the outsides of their "hands."

When aggravated, tamanduas communicate by hissing and releasing an unpleasant scent from their anal gland. If threatened while residing in the trees, it grasps a branch with its hind feet and tail, leaving its arms and long, curved claws free for combat. If on the ground, it backs up against a rock or tree and wrestles the opponent with its powerful forearms.

Tamanduas have small eyes and poor vision. Instead, they rely more on their sense of smell and hearing. Tamanduas are able to extract their prey by using their extremely strong forearms to rip open nests. They lick up insects with their elongated snouts and rounded tongues, which can reach up to 40 cm in length.

These animals, though widespread, are uncommon. Claiming that they kill their dogs, tamanduas are often killed by hunters. They are also hunted for the thick tendons in their tails, which are used to make rope. Tamanduas are sometimes used by Amazonian Indians to rid their homes of ants and termites.

Besides the tamanduas, there are two other anteaters, the Giant Anteater and the Silky Anteater. Tamanduas are much smaller than the Giant Anteater, which lives on the ground and is found in a wide range of habitats, including grasslands, deciduous forests and rainforests. The Giant Anteater eats mostly ants and termites. Tamanduas are larger than the Silky Anteater, which ranges from extreme southern Mexico to Brazil, and possibly Paraguay, and is completely arboreal. It eats mostly ants and termites.

The word tamandu√° is Tupi for "anteater", and in Tupi and Portuguese refers to anteaters in general. The tamandua is called in those languages tamandu√°-mirim (mirim means "small").
