The Egyptian slit-faced bat gets its name from the distinctive slit, or lobed groove, which runs down the centre of the face, from between the eyes to the snout (2). This bat has long fur, which is brownish to brown-grey on the back, but a paler brown to dirty-white colour on the underside (2) (4). It has impressive, large, elongated ears which stand straight up from the head, and are characteristically larger than those of other Nycteris species (2). The tragus, the fleshy projection which covers the entrance of the ear (and a useful feature for differentiating between different bat species), is small, rounded and simple. The tail of the Egyptian slit-faced bat is also unique, being long with a T-shaped tip, and it is completely enclosed within the flight membrane, which stretches between the two hind legs (2). The large wings, which are rounded at the tip (4), along with the large tail membrane, suggest this bat flies slowly but can quickly change direction with great skill (5).
