The Shortest-Lived Mammals?
In short: Male antechinus and their once-breeding relatives die at about 11.5 months after a single mating period, while the common shrew's lifespan averages 13 months in the wild: two short mammal lives, measured in two different ways.
A 1:25 short film in the series “Nature: How Long Can It Live?”, narrated by intellect_voice_01.
