At barely 2″ long (about 47 mm, to be exact), the pygmy jerboa is one of the smallest mammals in the world. While there are a few different species spread out across Central Asia and China, it is best loved in Kazakhstan, where it is featured on postal stamps!
Scientists believe their diminutive size is due to the species separating off from the larger rodent family and settling in the lands it now resides in today.
According to the International Union for the Conservation of Nature’s Red List of Threatened Species, they’re native to the deserts of Pakistan.
Their comically large feet allow them to leap around like kangaroos, and they have highly sensitive hearing so they can detect predators approaching, according to ABC News.
