The wrinkle-faced bat is a frugivore (fruit eater) and is actually classified as a member of the leaf-nosed bats, despite not having a leaf nose. Molecular phylogeny is wild. They have the strongest bite force in relation to body size of all known bats and their short, broad heads are thought to allow them to eat a wider range of fruits.

Males grow a skin flap that partially covers their faces. When not in use for adorable convenience store robberies, males lower their masks to show females they're interested in getting it on. Seriously.
