Saccopteryx bilineata, the greater sac-winged bat, lives in Central and South America. They are among the most common bats actually seen in the rainforest because they often roost on the outside of large tree buttresses. They are aerial insectivores that emit echolocation calls through the mouth. The long nose and upper lip are highly mobile, facilitated by a “free” (unfused and unsutured) premaxilla that can shift upward when the mouth is opened to enlarge the gape.
