The Damara woolly bat is a small member of the Vespertillidonae, the largest and most widespread family of bats. Covered in long, soft hair with curly tips, the woolly bats are most easily recognised by their grizzly appearance and by a fringe of hair which sits around the hind edge of the naked, reddish-brown interfemoral membrane, which stretches between the legs (3). Rich reddish-brown hair covers the upperparts, while the greyer, less grizzled appearance of the underparts, combined with a slightly larger size, distinguishes the Damara woolly bat from its close Southern African relative, the lesser woolly bat (Kerivoula lanosa) (4). The wings are short and broad, making flight slow (4), and the ears are large and funnel-shaped, ending in rounded tips. The tragus, a fleshy projection covering the inner ear, is long and pointed (3). Lacking a noseleaf on its simple muzzle, the Damara woolly bat instead emits, or ‘shouts’, ultrasonic signals through its mouth (4).
