The longtail cusk (Brosmolus longicaudus) is a species of viviparous brotula native to the reefs around Australia. This species grows to a length of 5.8 centimetres (2.3 in) SL.
It is a benthic species likely living in inshore waters around the Indio-Pacific with hard substances, though its depth range is unknown.
