It is hard to guess what a European free-tailed bat weights. But we have the answer:
An adult European free-tailed bat (Tadarida teniotis) on average weights 28 grams (0.06 lbs).
The European free-tailed bat is from the family Molossidae (genus: Tadarida). When reaching adult age, they grow up to 8.4 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 European free-tailed bat (Tadarida teniotis, sometimes given as Tadarida insignis) is a species of free-tailed bat found in the Old World. Other common names include the bulldog bat and the mastiff bat because of the presence of wrinkling on the snout. This bat is found in the Mediterranean region of Europe and in scattered locations across Asia at altitudes from sea level to 3100 m. The range of distribution is from the Canary Islands and Madeira through the whole Mediterranean area, Asia Minor, the Caucasus and the Middle East. In the north to southern France, southern Switzerland, Croatia and Bulgaria. It was reported from Korea in 1931, but has not been sighted on the Korean Peninsula since that time. Populations in Japan, Taiwan and Korea are now considered to be a separate species Tadarida insignis.
