Greater sac-winged bat

"Saccopteryx bilineata", is a bat of the family Emballonuridae native to Central and South America. They are the most common bats seen in the rainforest, as they often roost on the outside of large trees. They are insectivores and use echolocation calls through the mouth to track their prey. The long nose and upper lip are highly mobile and can shift upward to enlarge the mouth opening.
