Quick Summary

A nose leaf is a skin expansion on the nose of certain bats that resembles a leaf. This structure is believed to have a delicate tactile function. Leaf-nosed bats, found in both the New World and Old World, belong to the families Phyllostomidae and Hipposideridae. The nose leaf's exact purpose is unknown, but it may assist in echolocation. The complexity and shape of the nose leaf vary by family and are associated with nasal emission of orientation signals, suggesting it might influence sound output.123
