Spix's disk-winged bat
（重定向自Thyroptera tricolor）
Spix’s disk-winged bat (Thyroptera tricolor), is an insectivorous species of bat in the family Thyropteridae. Although this species is unevenly dispersed, it is widespread and is therefore considered as having a “least concern” status on the conservation list. The most prominent anatomical feature of this bat, separating it from other bats, is the presence of disks on its thumbs and hind feet. These circular disks act as suction cups, allowing the bats to cling onto and move along smooth surfaces.
