This species grows to a length of 30cm (10inches) TL. This species is one of two member of its genus, the other being Selachophidium americanum.[1] The barbed brotula has been found to have an ossified swelling of bone in the back of the skull that is connected to the pectoral girdle, vertebral column, and gas bladder via soft tissue.
