How many baby Common vampire bats are in a litter?
A Common vampire bat (Desmodus rotundus) usually gives birth to around 1 babies.With 1 litters per year, that sums up to a yearly offspring of 1 babies.
Each of those little ones spend around 212 days as a fetus before they are released into the wild. Upon birth, they weight 6 grams (0.01 lbs) and measure 2.8 cm (0′ 2″). They are a member of the Phyllostomidae family (genus: Desmodus). An adult Common vampire bat grows up to a size of 7.8 cm (0′ 4″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The common vampire bat (Desmodus rotundus) is a small, leaf-nosed bat native to the Latin america. 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 night while they are sleeping. It then uses its razor-sharp teeth to cut open the skin of its hosts and lap up their blood with its long tongue.The species is highly polygynous, and dominant adult males defend groups of females. It is one of the most social of bat species with a number of cooperative behaviors such as social grooming and food sharing. Because it feeds on livestock and is a carrier of rabies, the common vampire bat is considered a pest. Its conservation status is categorized as Least Concern by the International Union for Conservation of Nature (IUCN) because of “its wide distribution, presumed large population tolerance of a degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.”
