Overview
Peters’s Flat-headed Bat (Platymops petrophilus) is an extraordinary, highly specialized free-tailed bat native to the rocky landscapes and savanna inselbergs of eastern and southern Africa. Renowned among mammalogists for its astonishingly compressed cranial anatomy, this agile insectivore possesses a paper-thin profile that permits it to squeeze deep into millimeter-thin rock cracks where predatory birds and snakes cannot penetrate.
Biology and Physical Characteristics
Platymops petrophilus features one of the most extreme skeletal adaptations among all mammals. Its skull is remarkably flattened dorsoventrally, measuring barely one-third of an inch thick, with flattened auditory bullae and wide-set, forward-pointing ears. Its leathery tail projects well beyond the interfemoral membrane, typical of molossids, and its feet bear specialized friction pads and tactile bristles that provide exceptional grip on glassy-smooth granite surfaces inside deep vertical cracks.
Behavior and Ecology
Exclusively nocturnal and lithophilic, Peters’s flat-headed bat roosts in small colonial groups of two to a dozen individuals within exfoliating granite slabs and sandstone fissures. At dusk, it drops swiftly from cliff ledges, utilizing high-frequency, narrow-band echolocation pulses designed for fast aerial hawking in open savanna airspace. Feeding on flying coleopterans, dipterans, and winged termites, it consumes a substantial percentage of its body mass each night before scuttling back into its crevice home.
Conservation and Human Impact
Evaluated as Least Concern by the IUCN, Platymops petrophilus benefits from remote, inaccessible cliff and rocky kopje habitats across its broad geographical distribution. Potential localized threats include commercial quarrying of granite inselbergs and disruption of waterholes by intense livestock grazing. Its presence across numerous national parks, such as Kruger in South Africa and Matobo in Zimbabwe, safeguards core breeding colonies.
Interesting Factoid
The skull and ribcage of Peters’s flat-headed bat are so radically flattened that the bat can scurry effortlessly into granite crevices narrower than the width of an ordinary pencil!
