"Over the last two decades there have been several longevity records of bats that have exceeded 20 years, mostly corresponding to Holarctic hibernating species, whereas such data of tropical bats is still scarce. Here we report the first longevity record for the Gervais´s Funnel-eared Bat, Nyctiellus lepidus (Gervais, 1837) (family Natalidae). We recaptured a male individual that had been banded 16.9 years previously in the same cave in Central Cuba. This species is endemic to Cuba (including Isla de la Juventud) and the Bahamas and is an obligate cave-dwelling bat. Weighing nearly 2 grams, N. lepidus is one of the world’s smallest bats. Based on longevity quotient (the ratio of observed to predicted longevity), we estimate that its lifespan is 3.9 times longer than expected for its body mass. This longevity record constitutes one of the longest in a non-hibernating insectivorous bat." Thank you Carlos.
