Did you know Rabbits (and other lagomorphs) have an extra set of teeth!
Rabbits have a pair of tiny incisors behind their top incisors.
These are called peg teeth or secondary maxillary teeth.
When the mouth is closed, the lower incisors slot between the upper incisors and the peg teeth. The teeth rub against each other, keeping both upper and lower incisors chisel-sharp.
