DENVER — Denver Zoo officials say a southern tamandua, a type of anteater, is pregnant and expected to give birth around March.

The Denver Post reports ( ) the typical gestation period for a tamandua is between 130 and 150 days, during which time the zoo says the anteater named Rio will be getting "top prenatal care," including an increased diet and a behind-the-scenes dwelling.

Rio and her mate, Quito, are never on exhibit at the zoo, but are available for up-close encounters, outreach visits and VIP tours.

Southern tamanduas live in South America and have tongues that are up to 16 inches long so they can reach termites and ants.
