The word, rabbit bandicoot, refers to a small marsupial animal native to Australia. It is also known by several other names, including bilby, rabbit-eared bandicoot, and lesser bilby. These synonyms describe the physical features or behaviors of the animal. For instance, bilby is derived from the Warlpiri language and means "long nose." The rabbit-eared bandicoot is named after its long ears, which are similar to those of rabbits. The lesser bilby, on the other hand, is a smaller and rarer species compared to the bilby. These synonyms not only add variety to the language but also reflect the cultural diversity of the names given to the animal.
