How big does a Pacific sheath-tailed bat get? Here is an overview over the average adult age:
A grown Pacific sheath-tailed bat (Emballonura semicaudata) reaches an average size of 4.7 cm (0′ 2″).
When born, they have an average size of 0 cm (0′ 0″). A full-grown exemplary reaches roughly 6 grams (0.01 lbs). The Pacific sheath-tailed bat (genus: Emballonura) is a member of the family Emballonuridae.
As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.
The Pacific sheath-tailed bat or Polynesian sheath-tailed bat (Emballonura semicaudata) is a species of sac-winged bat in the family Emballonuridae found in American Samoa, Fiji, Guam, Micronesia, Palau, Samoa (where it is called pe’a vai, tagiti or pe’ape’a vai), Tonga, and Vanuatu. Its natural habitat is caves. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation. It is threatened by habitat loss. There are estimated to be approximately 500 individuals of E. s. rotensis, a subspecies of the highly fragmented Emballonura semicaudata. Due to its dependence on forests and caves for roosting, it is known to roost in only three caves currently, E. s. rotensis is vulnerable to changes in the surrounding demographic and environmental changes reflective of indirect impacts caused by invasive species, in this case goats. Goats limit the carrying capacity of E.s. rotensis.
