Taphozous: Tomb Bats A wing pocket or pouch is present in all species. Most species also have a glandular sac in the lower throat. This sac is more highly developed in the males than in the females and may be entirely absent in the latter. The species T. melanopogon lacks this sac and instead has small pores that open into the area where the sac would be.
