Nycteris grandis grandis, the Large slit-faced bat, is native to south central Africa. It is a member of the family Nycteridae, which is characterized by a large, complex slit-like structure on the face above the nose. The function of this slit, which is surrounded by leaf-like foliations, is unknown. Slit-faced bats are primarily insectivorous, but may occasionally eat small vertebrates (such as frogs or mice) if given the opportunity. They sometimes catch their prey in the air, but frequently glean their prey from surfaces. Their large ears are apparently used to listen for prey-generated sounds (such as the sound of an insect landing on vegetation), which they use to help locate potential food items.
