Indexes of skeletal measurements are used to compare body proportions in Hyaenidae, Canidae and Felidae. Hyaena and Crocuta are characterized by a long neck and long forelimbs. The humerus is relatively short and the radius and metacarpal bones are long. In the the os femoris is long and the tibia short. The proportions are adapted to carry large and heavy prey and provide maximum static stability. Proteles cristatus which mainly feeds on termites and insects has the long neck and forelimb in common with the other Hyaenidae, but its hindlimbs are longer and the length of the limbsegments reveals more canid proportions.
骨骼测量指标用于比较鬣狗科、犬科和猫科动物的身体比例。斑鬣狗属和斑鬣狗的特征是颈部和前肢较长。肱骨相对较短,桡骨和掌骨较长。股骨较长,胫骨较短。这种比例适合搬运大型沉重猎物,并提供最大的静态稳定性。主要以白蚁和昆虫为食的土狼与其他鬣狗科动物一样具有长颈和前肢,但其后肢更长,肢体节段的长度显示出更多犬科动物的比例特征。
