The ghost bat—Macroderma gigas—is a flying mammal found in isolated colonies in northern Australia. They are the only Australian bat to prey on larger animals, birds, reptiles and other mammals, and use a combination of sight, hearing and echolocation while waiting at a perch to ambush the prey. The wing membrane and bare skin is pale in colour, the fur is light or dark grey at the back and paler at the front. A prominent and simple nose-leaf is present, the ears are elongated and joined at lower half, the eyes are large and dark. The first description of the species was published in 1880, its recorded range has significantly contracted since that time.
