Emballonurids are known as sac-winged or sheath-tailed bats. The first of these names describes the glandular sac usually found on the propatagium (leading edge of the wing) in many species. This gland produces a scent used in social displays and to mark territories. Males of some species have a pouch at the base of the throat that may serve a similar function. Emballonurids are also known as sheath-tailed bats because their tail appears to be sheathed in a membrane (uropatagium or interfemoral membrane). The tip of the tail protrudes from the top of this membrane and does not extend for the full length of the membrane.
This family includes 13 genera and 47 species. Their range is tropical and subtropical in both the Old and the New World.
