It is hard to guess what a Pygmy long-eared bat weights. But we have the answer:
An adult Pygmy long-eared bat (Nyctophilus walkeri) on average weights 4 grams (0.01 lbs).
The Pygmy long-eared bat is from the family Vespertilionidae (genus: Nyctophilus). When reaching adult age, they grow up to 9.3 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 pygmy long-eared bat, species Nyctophilus walkeri, is a vespertilionid bat, found in the north of the Australian continent. An insectivorous flying hunter, they are one of the tiniest mammals in Australia, weighing only a few grams and one or two inches long.
