The tail is armoured, but the face, neck and underparts lack armour and are sparsely covered with pale fur. The legs are short and the four toes on the forefeet and five on the hind feet are long with strong claws. Adults grow to a maximum head-and-body length of around with a tail of up to , and a weight of up to .

Distribution and habitat

This armadillo is

to the tropical northern part of South America. Its range includes lowland parts of Venezuela and Colombia where its altitudinal range is above sea level. Its habitat is the

, a vast grassy plain that periodically floods.

Ecology

The species has a home range somewhere between . It emerges to forage at dawn and dusk and feeds on small invertebrates such as ants, termites and beetles. In Venezuella, it breeds between October and March. The litter size is usually four. As is the case with other members of '' Dasypus'', all the embryos develop from a single

Status

The floodplains on which ''D. sabanicola'' lives are increasingly being used for the production of biofuels, for agro-industry and for tree plantations. This reduces the quantity and the quality of the habitat available to the armadillo. Population counts have not been done, but the animal is hunted for food, and there are reports from people living in the area that it is being seen less often. For these reasons, and as a precautionary measure, the
