Vampire bats sharing food. Regurgitated food sharing in common vampire bats has been studied in both the lab and field, and is predicted by kinship, association, and reciprocal help [27] In a field study conducted in Costa Rica from 1978 to 1983, [21] vampire bats frequently switched between several roost trees and co-roosted with kin and non ...
It is the largest-known vampire bat to have ever lived. The length of its skull is 31.2 mm (1.23 in), and its humerus length was approximately 51 mm (2.0 in), as compared to the extant common vampire bat at 32.4–42.4 mm (1.28–1.67 in). Its skull was long and narrow, and its face had an upturned snout. [6]
It preys on other bats opportunistically, and it is known to eat bats out of researchers' mist nets. Prey species include the highland yellow-shouldered bat, Geoffroy's tailless bat, Pallas's long-tongued bat, short-tailed fruit bats, the common vampire bat, and fruit-eating bats. [25]

The common vampire bat (Desmodus rotundus) is a small, leaf-nosed bat native to the Neotropics. It is one of three extant species of vampire bat, 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 ...
Desmodus is a genus of bats which—along with the genera Diaemus and Diphylla—are allied as the subfamily Desmodontinae, the carnivorous, blood-consuming vampire bats of the New World leaf-nosed bat family Phyllostomidae.
Their thumb is much shorter than that of the common vampire bat. Their forearms are 51–54 mm (2.0–2.1 in) long. The calcar is absent. Their dental formula is 1.1.1.2 2.1.2.1, for a total of 22 teeth; the common vampire bat has 20 teeth and the hairy-legged vampire bat 26, respectively. [7] It is the only bat species in the world with 22 ...
