It is hard to guess what a Seychelles sheath-tailed bat weights. But we have the answer:
An adult Seychelles sheath-tailed bat (Coleura seychellensis) on average weights 10 grams (0.02 lbs).
The Seychelles sheath-tailed bat is from the family Emballonuridae (genus: Coleura). When reaching adult age, they grow up to 6 cm (0′ 3″).
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 Seychelles sheath-tailed bat (Coleura seychellensis) is a sac-winged bat found in the central granitic islands of the Seychelles. It is an insectivorous bat, feeding primarily in forest clearings at night and roosting in communal roosts by day. Although previously abundant across the island group, it now only occurs on three islands. Its numbers have been declining to such an extent that the International Union for Conservation of Nature has listed it as being critically endangered. Increases in the cultivation of coconut palms in plantations, and the introduction of alien plant species, seem to have reduced the availability of insect food.
