Craniofacial indices still remain a useful means of early detection of the characteristic facial appearance of some syndromes. The cranio-facial and gross ocular morphometry of the male Greater cane rat (Thryonomys swinderianus) was studied using 9 adult males. A total of twenty seven parameters were determined for each head. The weights of the animals, the heads and both eyeballs were 1.969 ± 0.374 kg, 252 ± 36.89 g, and 1 ± 0.115 g respectively. Linear measurements were determined on each eyeball using digital vernier calliper, measuring rule and a piece of twine. Craniofacial parameters assessed included distance between medial canthi, height of the incisor, rima oris length, width and length of the pinnae. All measured parameters were correlated with the body weight. The highest positive correlation was observed between the body weight and the width of the head, while the heights of the two upper incisors showed the lowest negative correlation with the body weight. With increase in the use of wildlife as experimental animals, results from this study may find application in the field of comparative anatomy and pathological studies as well as in wildlife clinical applications.
