Best known for being first on any alphabetical listing of wildlife, an aardvark is a nocturnal, burrowing animal and the only living species in the order Tubulidentata.

Genetically, the animal can be considered a living fossil because of the ancient arrangement of its chromosomes. Aardvarks are excellent diggers and, bizarrely enough, elephants are one of their closest living relatives (although the relationship is very distant).
