What Is The Lifespan Of A Vampire Bat ?

The lifespan of a vampire bat is around 12 years. For a bat that is small in size, this is quite a lifespan. The gestation period of the vampire bat is quite long, and it extends anywhere from 90 days to 120 days. When a vampire bat is born, it weighs between 0.18 ounces and 0.25 ounces. However, 3 weeks after birth, the weight of the vampire bat doubles and reaches between 0.35 ounces and 0.49 ounces. The vampire bat reaches full maturity after 300 days of being born and an adult vampire bat weighs anywhere from 0.98 ounces to 1.06 lbs. In captivity, a young bat is dependent on the mother for a period of 9 months.

Out of all the species of bats, the vampire bat is considered to be the most intelligent as it has the ability to learn the different flight routes it takes. These bats tend to live in colonies, and the size of a colony can range from just 6 bats to thousands of bats. (See Reference 1)

Besides humans, the only other animal to show unselfish behavior is the vampire bat. When a vampire bat that has not fed in the night begs for food, other vampire bats, especially females, have no qualms about regurgitating the blood and allowing that unfed bat to feed. Even nursing vampire bats are known to share their milk with males that are hungry. In addition, when a baby vampire bat is orphaned, it is normally adopted by an older female in the colony.
