What is the maximal age a Mexican free-tailed bat reaches?
An adult Mexican free-tailed bat (Tadarida brasiliensis) usually gets as old as 15 years.
Mexican free-tailed bats are around 90 days in the womb of their mother. When born, they weight 3 grams (0.01 lbs) and measure 3.4 cm (0′ 2″). As a member of the Molossidae family (genus: Tadarida), a Mexican free-tailed bat caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 4.1 cm (0′ 2″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The Mexican free-tailed bat or Brazilian free-tailed bat (Tadarida brasiliensis) is a medium-sized bat native to the Americas, regarded as one of the most abundant mammals in North America. Its proclivity towards roosting in huge numbers at relatively few locations makes it vulnerable to habitat destruction in spite of its abundance. The bat is considered a species of special concern in California as a result of declining populations. It has been claimed to have the fastest horizontal speed (as opposed to stoop diving speed) of any animal, reaching top ground speeds over 100 mph (161 km/h); its actual air speed has not been measured. The Texas Legislature designated the Mexican free-tailed bat the state mammal (flying) in 1995.
