The narrowbar swellshark (Cephaloscyllium zebrum) is a rare species of catshark, and part of the family Scyliorhinidae, known only from two specimens collected near Flinders Reef off northeastern Australia.

In 2008, this species was formally described by Peter Last and William White in a CSIRO publication, and given the specific epithet zebrum in reference to its unique color pattern.

[2] The narrowbar swellshark has only been found at a depth of 444–454 m (1,457–1,490 ft) on the upper continental slope, near Flinders Reef off the Australian state of Queensland.

[1] A small Cephaloscyllium species at around 44 cm (17 in) long, the narrowbar swellshark has a robust body and a short, broad, and flattened head.

The snout is rounded, with the nostrils preceded by laterally expanded skin flaps that do not reach the long and narrow mouth.

[3] The International Union for Conservation of Nature (IUCN) has listed the narrowbar swellshark under Data Deficient until more information is available, while noting that there is little fishing activity in the region where it occurs.
