The Javan mastiff bat, also known as Otomops formosus, is a species of megabat that is native to Southeast Asia. It is known for its large size, with individuals reaching up to 12 cm in body length and weighing up to 30 g. These bats are nocturnal and feed primarily on insects, using their large size to their advantage to capture and consume prey.

Javan mastiff bats are highly social animals, roosting in large colonies that can number in the hundreds or thousands of individuals. They are known to be very vocal, communicating with each other through a variety of calls and chirps.
