Of the three extant species of zebra, two have 36 or 40 teeth, depending on sex, and one has 42 teeth. Their teeth patterns are very similar to those of domestic horses. As with domestic horses, females often lack canines.
The plains zebra, also known as Burchell's zebra, is the most numerous of the three species and has a maximum of 40 teeth. The mountain zebra, an endangered species, also has a maximum of 40 teeth. Grevy's zebra differs, with a maximum of 42 teeth. All three are grazers with complex cheek teeth specialized for breaking down abrasive and fibrous grass.
