Disklike structures on the wrists and ankles of Spix's disk-winged bat adhere to smooth leaves using suction adhesion.

Edit Hook


"Several of the smallest bats, for instance, use [suction adhesion] to cling to smooth leaves, with disklike structures on wrists and ankles. In the 3.5-gram Thyroptera tricolor of Central America, suction provides the main mechanism; these bats' minimal reliance on other schemes such as the two kinds of wet adhesion that follow [Stefan and capillary] limits their ability to cling to anything but smooth surfaces (Riskin and Fenton 2001)." (Vogel 2003:427)
