Brandt's Bat: researchers once documented a case in which a Brandt's bat had survived in the wild for more than 40 years, making this the longest-living bat species in the world

In 1964, a wild Brandt's bat (Myotis brandtii) was captured, banded, and released by researchers in the Biryusa region of Siberia. The very same bat was eventually recaptured by another team of researchers in 2005; it would have been at least 41 years old by then, making it the oldest bat ever recorded.

The previous record-holder was also a Siberian Brandt's bat (with an estimated age of 38 years).

There are twelve other species within the genus Myotis that have been documented living past the age of 20, but the lifespan of the Brandt's bat is exceptionally long, especially compared to other small mammals.

This species (and the longevity of a few other bat species) defies our conventional understanding of the relationship between an animal's size and its lifespan -- smaller animals normally have a much shorter lifespan compared to large animals, partly due to their higher metabolic demands, but these bats represent a rare exception to that rule. In fact, with an average weight of just 4 to 8 grams (which is roughly the combined weight of 2 or 3 pennies), the Brandt's bat has the longest lifespan of any mammal relative to its size.

Research suggests that its increased lifespan may be at least partially linked to a mutation in two of the genes that are related to growth. This article describes the results of one particular study:

Genes for two proteins involved in growth — called growth hormone receptor (GHR) and insulinlike growth factor 1 receptor (IGF1R) — showed changes that also appear among other long-lived bat species. Previous studies in mice and other animals suggest genetic changes in GHR and IGF1R are linked with longevity. For instance, mice with mutations in GHR live twice as long as normal mice, said study researcher Vadim Gladyshev, a geneticist at Brigham and Women's Hospital in Boston.

These same genetic changes also may be responsible for the bats' small size ...

"We think the bat's life span is, in part, an unintended consequence of its small body size."

There are a few other factors that may also play a role:

Brandt's bats also hibernate and roost in caves — behaviors that may help them avoid predators and extreme weather conditions, and contribute to their longer life span, the researchers said. The Brandt's bat also takes a relatively long time to reach maturity, and it does not produce many offspring — two characteristics seen in larger, longer-living mammals.

Note: nearly all of the articles that I came across refer to the 41-year-old bat as a "Brandt's bat," but at least one other source uses the term "Siberian whiskered myotis," instead. That term simply refers to the Siberian variety of the Brandt's bat (subspecies Myotis brandtii sibiricus) in particular.

if annie is a bat, do they ever hang out upside down? i miiiight have gotten some details wrong/forgotten if you answered this one already

Hello Null!! And yes he does, he’s a climber and will hang upside down any chance he gets. He got so used to to being up high in his father’s breast pockets as a baby that he has no fear of heights(that’s high for a little guy.

Claude will let Annie climb and crawl all over him and not bat an eye, happy to state his son’s affection, even in highly inappropriate places like a party or dinner. Sebastian is the fun police and enforces his manners like he does with the Phantomhive servants., and lectures his mates spoiling behavior. (That one pic of the mom scolding the son and then also the husband….will draw that soon.) but after all is said and done Sebastian is giving his little one fruit and some dark chocolate.

Annie gives Ciel a headache sometimes with how long he hangs upside down.

Also wanted to saw what kind of bat his bat form is based on which is the Brandt’s Myotis or Brandt’s bat. Look how floofy they are!!!!

🦇Bat Fact! Do you know of the Whiskered Bat (Myotis mystacinus)? This European microbat is often confused for Brandt’s Bat (Myotis brandtii). This bat comes in at an average weight of 4-8g and an average lifespan of 4-5 years, though some individuals live to be 20 years old! Insectivorous, this bat feasts on moths, mayflies, dragonflies and more! Most Whiskered Bats will stay where they were born, barely migrating and roosting in nearby houses, old buildings, caves, and tunnels. They will often roost with Brandt's Bats but in separate colonies. This bat is listed as “Least Concern” by the IUCN🦇

Turning Back Time

With ageing populations and the increasing prevalence of age-related diseases, understanding how to stay healthy as we get older is critical. Inspiration could come from bats, which have an extraordinarily long lifespan for their body size. Brandt’s bats (Myotis brandtii, pictured) can live for over 40 years, nearly 10 times longer than expected for a mammal weighing only 7 grams. Key to the ageing process are telomeres, protective DNA repeats at the ends of chromosomes; in humans and most animals, these are progressively lost as cells replicate, ultimately causing cell death. By contrast, in Myotis bats, telomeres do not shorten with age. Moreover, while the enzyme telomerase protects telomeres in stem cells and many cancers, allowing cells to keep replicating, another mechanism is at work in these bats. Several genes associated with DNA repair may be involved, and could prove to be interesting targets for future research on ageing.

25) Nocek Brandta, Brandt's bat (Myotis brandtii) – gatunek ssaka z rzędu nietoperzy. W Polsce stwierdzany był w całym kraju, choć jego rozmieszczenie jest bardzo nierównomierne. W niektórych kompleksach leśnych (np. w Lasach Łukowskich na południe od Siedlec) jest jednym z najczęstszych nietoperzy stwierdzanych w okresie rozrodu. Z kolei na Pomorzu jest gatunkiem bardzo rzadkim, zaś jego rozrodu nie stwierdzono tam w ogóle. Generalnie jest częściej notowany w południowej części kraju, z wyjątkiem wysokich gór. W Tatrach spotykany jedynie sporadycznie, w przeciwieństwie do pospolitego tam nocka wąsatka. W Polsce jest objęty ścisłą ochroną gatunkową oraz wymagający ochrony czynnej, dodatkowo obowiązuje zakaz fotografowania, filmowania lub obserwacji, mogących powodować płoszenie lub niepokojenie.
