Deer Phalangeal Formula

There are two types of unguligrades when classifying them by their digits: artiodactyls and perissodactyls.  Artiodactyls such as this deer have an even number of digits, while perissodactyls such as a horse have an odd number of digits.  Unguligrades such as this deer have very specialized digits that have very litle mobility but have great strength.  This narrow pharyngeal formula allows deer to easily travel through thich brush and rough terrain withouth geting their feet tangled up.
