(rabbit) is a good representative of class-mammalia. Dentituion in all the mammals are heterodont (
dissimilar teeth). Canine is one, pointed in each maxillary of upper jaw and each dentary of lowar jaw. In rabbit and other herbivorous mammals, canines are absent. Hence, some parts of gums between incisors and other teeth remain teethless and called diastema.
Rabbit possesses three pairs of wall developed, sharp, chisel like incisors, two pairs in the premaxillaries of upper jaw and one pair in denteries of lowar jaw. Dental formula of rabbit is :
