Because the hairy-legged vampire bat feeds on bird blood and it is the most basal of living vampire bats, it is considered likely that the first vampire bats fed on bird blood as well. [15] Recent analyses suggest that vampire bats arose from insectivores, which discount the frugivore, carnivore, and nectarivore hypotheses of origin. [ 15 ]
The skulls of Pteropus species are composed of 24 bones, the snout is made of 7, the cranium of 16 and the mandible is a single bone. It has a large and bulbous braincase. Like all mammals, flying foxes have three middle ear ossicles which assist in transmitting sound to the brain. Flying fox skulls continue to develop after they are born.

Skull of the greater horseshoe bat, showing the prominent rostral inflation on the snout. All horseshoe bats have large, leaf-like protuberances on their noses, which are called nose-leafs. [10] The nose-leafs are important in species identification, and are composed of several parts. [20]
This bat is found in various countries in and around Central America. It eats fruit but is not classified within the fruit bats, and is instead classified as a leaf-nosed bat even though it does not have a leaf nose. [2] It has an unusually shaped skull which is thought to allow it to eat a wider range of foods than other bats. [3]

It is one of three extant species of vampire bats, the other two being the hairy-legged and the white-winged vampire bats. The common vampire bat practices hematophagy, mainly feeding on the blood of livestock. The bat usually approaches its prey at ...
The big brown bat belongs to the serotinus group, which is defined by having a large, elongate skull, flat braincase, and a long snout. [26] In a study of the evolutionary relationships of some Eptesicus species, the big brown bat was most closely related to the two other species from the Americas: the Argentine brown bat and the diminutive ...
