It is hard to guess what a Davy’s naked-backed bat weights. But we have the answer:
An adult Davy’s naked-backed bat (Pteronotus davyi) on average weights 9 grams (0.02 lbs).
The Davy’s naked-backed bat is from the family Mormoopidae (genus: Pteronotus). It is usually born with about 1 grams (0 lbs). When reaching adult age, they grow up to 22.9 cm (0′ 10″). Normally, Davy’s naked-backed bats can have babies 1 times a year.
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.
Davy’s (lesser) naked-backed bat (species Pteronotus davyi) is a small, insect-eating, cave-dwelling bat of the Order Chiroptera and Family Mormoopidae. It is found throughout South and Central America, including Trinidad, but not Tobago, Guyana, Suriname, or French Guiana. Specimens of this bat had been found infected with rabies in Trinidad during the height of that’s island’s vampire-bat transmitted rabies epidemic of the early half of the 20th century, but not in recent times.
