Animal Weight

How much does a Gray bat weight?

It is hard to guess what a Gray bat weights. But we have the answer:

An adult Gray bat (Myotis grisescens) on average weights 10 grams (0.02 lbs).

The Gray bat is from the family Vespertilionidae (genus: Myotis). It is usually born with about 2 grams (0 lbs). They can live for up to 39.25 years. When reaching adult age, they grow up to 9.5 cm (0′ 4″). On average, Gray bats can have babies 1 times per year with a litter size of 1.

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 gray bat (Myotis grisescens) is a species of microbat endemic to North America. The creature once flourished in caves all over the southeastern United States, but due to human disturbance, gray bat populations declined severely during the early and mid portion of the 20th century. At one cave alone, the Georgetown Cave in northwestern Alabama, populations declined from 150,000 gray bats to 10,000 by 1969. 95% of gray bats now only roost in 9 caves. M. grisescens has been listed as federally endangered by the U.S. Fish and Wildlife Service since 1976, and is protected under the Endangered Species Act. Gray bat populations were estimated at approximately 2 million bats around the time they were placed on the Endangered Species list. By the early 1980s populations of gray bats dropped to 1.6 million. With conservation efforts in place, in 2002, gray bat populations were estimated to have reached 2.3 million.
