Crawshay's zebra (Equus quagga crawshayi), is one six recognised subspecies (including the extinct Quagga) of the more widespread 'plains zebra'. Although regularly seen in the Luangwa Valley, and often referred to as being unique to the area, it is also found in Malawi, Tanzania and northern Mozambique. As well as having narrow stripes compared to other forms of the plains zebra, Crawshay's zebras are also distinguished from other subspecies in that their lower incisors lack an infundibulum (the funnel-like centre of a tooth that is filled with cementum) which is notably found in the incisors of other horses and equines.
