It is hard to guess what a Yellow-lipped bat weights. But we have the answer:
An adult Yellow-lipped bat (Eptesicus douglasorum) on average weights 5 grams (0.01 lbs).
The Yellow-lipped bat is from the family Vespertilionidae (genus: Eptesicus). When reaching adult age, they grow up to 8.2 cm (0′ 4″).
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 yellow-lipped cave bat (Vespadelus douglasorum) is a vespertilionid bat which only occurs in the Kimberley region of northwest Australia. The bat was first captured at Tunnel Creek in 1958 and a description published nearly twenty years later. Aside from observations of their physical characteristics, a preference for caves, and hunting insects over streams, little is known of the species.
