Molossidae (free-tailed bats; order Chiroptera, suborder Microchiroptera) A family of insectivorous bats in which the thick tail is surrounded by the uropatagium which forms a loose sheath, and projects below the edge of the uropatagium when the animal is at rest. The nose is simple, with no leaf, and in most species overhangs the jaw. The ears are heavy-looking and deeply folded. Molossids often form very large colonies in caves and roofs. They are of world-wide tropical and subtemperate distribution. There are about 12 genera, with about 90 species.
