UWA, Curtin university and Perth zoo researchers have discovered that Australian endangered ghost bats in the Pilbara (WA) eat over 46 different species.

Its diet is very diverse ranging from small mammals, birds, reptiles and amphibians.

Researchers used a new approach by combining two methodologies: DNA analysis of faecal pellets and classification of dried food remains.

Ghost bats are decreasing with less than 10,000 remaining in the wild. The results provide crucial information for the conservation management of this iconic Australian species and its habitat. 

Ghost bats are the largest microbats in Australia and the second largest in the world with a wingspan of 60 cm and weight up to 170 grams.

They receive their name due to their pale grey colour and “ghostly” appearance. They are top-level predators and very important for the ecosystem.
