These SE Asia and Oceania natives are compact-bodied with triangle heads facing up

These bats are found in tropical and subtropical regions throughout the world. They also use echolocation to find their prey and make sense of the surrounding environment; the echolocation signals of some of these species are unusual as they can also be heard by humans.

Only two member species of this genus, the Seri’s sheath-tailed bat and the Pacific sheath-tailed bat are of particular concern right now when it comes to conservation status. They are categorized as Vulnerable and Endangered, respectively.
