Crested porcupine - Wikipedia

ADW: Hystrix cristata: INFORMATION
The animal's skull morphology is characteristic in several ways: (1) the infraorbital foramen is greatly enlarged so that portions of the masseter extend through it and arise from the frontal side surface of the snout (hystricomorphous condition); (2) the angular process is inflected on the lower jaw; (3) the nasal cavity is enlarged; (4 ...
