Three Banded Armadillo

(Tolypeutes matacus)
Order: Xenartha
Family: Dasypodidae
Genus: Tolypeutes
Species: Tolypeutes matacus

HABITAT AND RANGE: There are two species of three-banded armadillos. The species, T. matacus lives in central and eastern Bolivia, the Mato Grasso of Central Brazil, chaco region of Paraguay, northern and central Argentina. They are found in grassy or marshy areas between scattered forestland. This armadillo does not appear to dig its own burrows, but instead uses abandoned anteater burrows as shelter. The species T. tricinctus lives in tropical forests on chalky grounds, and in the Caatinga and Cerrado of Brazil.

PHYSICAL CHARACTERISTICS: Three-banded armadillos are blackish brown in color. Most individuals have three movable bands, but some have only two bands and others have four. The head and body length can range from 8.5 inches to 12 inches in length, with a 2-3 inch tail. The three-banded armadillo can weigh 2-3.5 pounds. The second, third and fourth toes of the hind foot are grown together, almost like a hoof. The first and fifth toes remain separate. T. matacus has four toes on the fore foot, and T. tricinctus has five. At the Ross Park Zoo we have the species of Tolypeutes matacus.

ADAPTATIONS: Members of the genus tolypeutes are the only armadillos that can completely enclose themselves in their own shell by rolling into a ball. The large front and rear portions of the shell are not attached to the skin on the sides, providing ample free space to fit the head, legs and tail into the shell when they are rolled up. Three-banded armadillos generally walk on the tips of their foreclaws, even when running. These claws on the forefeet are very strong. They are primarily solitary, although groups of up to 12 have been observed sharing the same den site during cold spells.

DIET: Three-banded armadillos principally eat beetle larvae, although ants and termites are an important portion of the diet during the dry season (July to November). Insects are obtained by burrowing into ground nests or under the bark of rotting trees. Armadillos also include a significant amount of fruit in their diet during the wet season.

REPRODUCTION AND DEVELOPMENT: Armadillos generally have litters between November and January, where after a gestation period of 120 days on young is born. The young are born fully formed, resembling miniature adults, and can walk and roll into a ball immediately from birth. Young are weaned at 72 days, and are sexually mature at 9-12 months of age. Some individuals have lived 20 years or more in captivity.

STATUS IN WILD: They are stable in the wild.
