Eerie-looking ghost bats have been caught on camera for the first time. The bats are filmed flying deep inside a cave in the Northern Territory in Australia.

Ghost bats are the largest type of predatory bat, and are thought to kill other bats on the wing.

Presenter Steve Backshall describes the action for the BBC series Deadly 60.

Deadly 60 is broadcast on the CBBC channel each Thursday at 1715.
