Animal Weight

How much does a Keen’s myotis weight?

It is hard to guess what a Keen’s myotis weights. But we have the answer:

An adult Keen’s myotis (Myotis keenii) on average weights 6 grams (0.01 lbs).

The Keen’s myotis is from the family Vespertilionidae (genus: Myotis). They can live for up to 18.5 years. When reaching adult age, they grow up to 9.5 cm (0′ 4″). Normally, Keen’s myotiss can have babies 1 times a year.

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.

Keen’s myotis (Myotis keenii) is a species of vesper bat. It is found in British Columbia in Canada and in Washington and Alaska in the United States. It is named after the Rev. John Henry Keen, who collected the specimen that formed the basis for the first scientific description of the species. Classification for Keen’s myotis formerly included the Northern long-eared Myotis (Myotis septentrionalis), resulting in older studies confusing the species for one another.
