Abstract

The aim of this project is to compare the ratio of (cranial volume; CV) to (skull volume; SV) in 25 mammalian species, 48 skulls (obtained from Chiang Mai Night Safari and Anatomy Laboratory, Faculty of Veterinary Medicine, Chiang Mai University, Chiang Mai). The cranial volume was measured by using filled sorghum seed volume which manually packing and filling through the cranial cavity. The SV was measured by use of Buoyancy force of Archimedes’s principle. The data of CV/SV (%) were collected for basic and advance study of zoology and veterinary medicine. The results found that skull of Spinner dolphin showed the highest ratio of CV and SV about 184.682%. Nevertheless, the ratio of CV and SV of each species seem to be depended on morphology, weight and density of skull and also cranial volume and the different ratio of CV and SV from the similar taxon have been recorded in family Cervidae and Antelope from family Bovidae.
