The Craniofacial Evolutionary Allometry (CREA) pattern can be seen in the dog family, Canidae, but only when considering prey size. Taking down large prey needs higher bite forces, so large prey hunters generally have shorter, more robust faces than small prey hunters. Because of these feeding differences, the largest species of all the Canidae, the wolf, has a shorter face than the largest fox species, even though the fox is smaller.
