| aardvark |
a large mammal with a long snout, long ears, a long tail, and with long fur mostly around its legs. Aardvarks are active at night, when they use their powerful claws to dig open ant or termite nests. They catch their food with their long, sticky tongue. Aardvarks live in southern and central Africa. Although they are sometimes called anteaters, aardvarks are not closely related to any other kind of mammal. |
