How much does a Common vampire bat weight?

It is hard to guess what a Common vampire bat weights. But we have the answer:

An adult Common vampire bat (Desmodus rotundus) on average weights 33 grams (0.07 lbs).

The Common vampire bat is from the family Phyllostomidae (genus: Desmodus). It is usually born with about 6 grams (0.01 lbs). They can live for up to 19.5 years. When reaching adult age, they grow up to 7.8 cm (0′ 4″). On average, Common vampire bats can have babies 1 times per year with a litter size of 1.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The average adult weight of a Common vampire bat is 33 grams (0.07 lbs)

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.”
