The Narrowbar Swellshark (Cephaloscyllium zebrum) is known only from two specimens trawled at 444–454 m off Flinders Reef, Queensland (Australia) in the Western Central Pacific. This species may be more widely distributed on the northeastern Australian continental slope than currently known. Nothing is known of its biology. Presently, there is low fishing effort in its area of occurrence. Distribution and status needs to be better defined, and given the lack of available information, an assessment of Data Deficient is appropriate.
