Molossidae is a family of bats commonly known as free-tailed bats. They are characterized by their long, narrow wings and a tail that extends beyond the tail membrane. These bats are found in various habitats around the world, often roosting in large colonies in caves, trees, or man-made structures. Free-tailed bats are known for their fast flight and agility, making them effective insect hunters. They primarily feed on moths and other flying insects, using echolocation to navigate and locate prey in the dark. This family includes several species, each adapted to different environments and climates.
