The aardvark is the only species in the family Orycteropodidae and the only living member of order Tubulidentata (“tube teeth”). The ordinal name refers to the tiny columnlike tubules of dentine that are fused together to constitute each molar; adults lack canine teeth and incisors. Although aardvarks look like anteaters, they are actually related to elephants (order Proboscidea), hyraxes (order Hyracoidea), and dugongs and manatees (order Sirenia);
The aardvark excavates branching burrows, usually 2–3 metres long but sometimes up to 13 metres, with several sleeping chambers. It abandons old burrows and digs new ones frequently, which thereby provides dens used by other species such as the African wild dog (Lycaon pictus). The aardvark’s diet consists almost entirely of ants and termites. At night it travels 10–30 km (6–19 miles), ambling along familiar paths in a zigzag fashion, pausing frequently to sniff and press its snout against the soil.
