Skull size

Different forest vegetations provide herbivorous small mammals with different resources, forcing adaptation since food habits depend on available resources. We expect differences in vegetation to be reflected in the size and shape of the skull and mandible as a result of potentially different feeding resources.

Anurans are the most suitable vertebrate group to see the development and also evolution in the skull, compared to other terrestrial vertebrates as they show highly derived morphology. For this reason, the cranium of anurans has been widely used for analyzing e.g., development and integration, evolutionary history, phylogenetic relationships, sexual dimorphism; and for taxon determination. We applied geometric morphometric techniques and then multivariate statistical analyses to see the skull size and shape variations in closely related Bufo species (B. bufo and B.

This study aims to elucidate geographic variation of C. dracula by comparing 23 craniodental measurements of the specimens from six localities on the mainland and island of Vietnam. We used principal component analysis (PCA) in order to evaluate variation in the size and shape of C. dracula.

This note presents the first record for Hipposideros-Khaokhouayensis in Vietnam. The species is a medium-sized leaf-nosed bat, and differs externally from all other hipposiderids previously known in the country by the shape of its internarial septum, characteristics of skull and teeth.

Giraffe characteristics: Very tall with long neck (elongated neck vertebrae) and long limbs. Bony prominences of neck vertebrae can be seen on the surface; brachiocephalicus and omotransversarius muscles, which usually cover the neck, begin low on the side of the neck, rather than up at the skull and first neck vertebra. Back line slopes downward toward rear. Usually three, permanent, bony "horns" in both male and female, covered with skin and fur.

Dog (canid) characteristics: Anatomy is the same in various domestic breeds and wild species—major difference is size and proportion (Dachshund to Great Dane). Typically with elongated skull—snout long and narrow (some domestic breeds have short muzzles). Large canines. Cheekteeth with sharp edges for shearing. Large, pointed ears—upright in all wild species and in many domestic breeds; hanging in some breeds. Deep chest (top to bottom); long, thin limbs. Five digits on front limb (thumb reduced), four on hind limb (big toe absent). Blunt, nonretractile claws. Walks on toes.
