Bilbies have the usual long bandicoot muzzle and big ears. They are about long. Compared to bandicoots, they have a longer tail, bigger ears, and softer, silky fur. The size of their ears allows them to have better hearing, and to radiate heat. They are nocturnal omnivores that do not need to drink water. They get their moisture from food, which includes insects and their larvae, seeds, spiders, bulbs, fruit, fungi, and very small animals. Most food is found by digging or scratching in the soil, and by using their very long tongues.
